ln what ways are solid- solid mixture categorized​

Answer:

rising action.

Explanation:

Rising action is a term used in literature to describe the corresponding portion of the story, that occurs immediately before the climax, by increasing its atmosphere or builds-up whereby the tension level surges.

Climax, on the other hand, is a form of the highest point major turning point in a story.

While falling action is the point where there is a quick decrease in tension level, and follows immediately after the climax

Resolution is also known as the final part of the story, it follows immediately after falling action.

Hence, when the problem within the story gets more intense and builds, this is the "Rising Action."

Answer:

Time of vaporization = 0.588 minutes

Explanation:

The latent heat of fusion is the heat required to change the substance from solid (ice) to liquid completely, without further increase in temperature.

The latent heat of vaporization is the heat required to change a liquid to gas completely, without an increase in temperature.

Latent heat of vaporization = 6.8 times Latent heat of fusion

This means that the time it takes for the latent heat of vaporization to complete vaporization is 6.8 times lesser than the time it takes for the latent heat of fusion to complete fusion

Time of vaporization = 6.8 times lesser than time of fusion

Time of vaporization = (time of fusion) ÷ 6.8

where: Time of fusion = 4 minutes

∴ Time of vaporization = 4 ÷ 6.8

Time of vaporization = 0.588 minutes

A plant powered by natural gas releases carbon dioxide

In an ecosystem, a plant powered by natural gas releases carbon dioxide which is toxic for the environment.

Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.

Energy enters the ecosystem through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.

Answer:

Does the nature of intermolecular forces present in different substance affect their boiling points?

Explanation:

In every scientific research there must be a dependent and an independent variable. These variables are easily deduced from the scientific question that is being investigated.

If a student is comparing the boiling points of different substances having different intermolecular forces, then his or her aim is to establish a relationship between the nature of intermolecular forces present (independent variable) and the observed boiling point of the substance (dependent variable).

This is aptly shown by the research question ' Does the nature of intermolecular forces present in different substance affect their boiling points?'

Options:

Is boiling point affected by the strength of particle attraction?

Is boiling point affected by the mass of the sample?

Is boiling point correlated to melting point?

Is boiling point the temperature at which a substance changes its state?

Answer:

4.14516129 g/mL

Explanation:

The density can be found with the following formula.

[tex]d= \frac{m}{v}[/tex]

where [tex]m[/tex] is the mass and [tex]v[/tex] is the volume.

We know the mass is 25.7 grams. We must find the volume.

The volume is equal to the volume of water that is displaced. Subtract the initial volume from the final volume.

⇒ final volume - initial volume

The initial volume is 35.5 mL and the final volume is 41.7 mL.

⇒ 41.7 mL - 35.5 mL

⇒ 6.2 mL

The volume of the aluminum piece is 6.2 mL.

Now we know the mass and the volume.

[tex]m= 25.7 g\\v=6.2 mL[/tex]

Substitute the values into the formula.

[tex]d=\frac{m}{v}[/tex]

[tex]d=\frac{25.7 g}{6.2 mL}[/tex]

[tex]d=4.14516129 g/mL[/tex]

The density of the aluminum sample is 4.14516129 g/mL

Answer:

it depends on the medium and the temperature

Explanation:

The speed of the sound wave has been majorly dependent on temperature and medium of propagation.

Speed can be defined as the distance traveled by the wave in a unit of time. The speed is a scalar quantity and has been independent of the direction.

The speed has been dependent on the medium of propagation of the wave, The transmission has been the transfer of sound energy, the medium with compact structure has been consisted of the higher speed with the medium having distinct particles.

The speed is also dependent on the temperature as the higher temperature has fast vibrating molecules and higher speed, while lower temperature has slow-moving molecules and lesser speed.

The speed of the sound wave has been majorly dependent on temperature and medium of propagation.

Answer:

This question appears incomplete but generally the answer is NO

Explanation:

Observation of the contents of an unlabeled jar depends solely on some of the physical properties of the content which is not good enough when identifying the contents of an unlabeled jar. This is because several substances have the same physical properties. For example, water and several acidic solutions appear the same in terms of colour and viscosity. Hence, a jar of water and a jar of hydrochloric acid cannot be differentiated by mere observation but with the use of litmus paper.

And a solution of hydrochloric acid and sulphuric acid cannot be differentiated by observation alone except a jar ammonia is brought close to the two jars (the one with hydrochloric acid will form a white fume with ammonia); hence relying on the chemical properties of both substances.

NOTE: Observation is done through sight, smell, feel, sound and taste without relying on another procedure/analysis to determine them.

   Drive only when needed. The best way to reduce the fuel consumption is to simply drive your car less. Drive your car only when you really need to. If you only need to travel a few blocks, consider walking or even riding a bicycle. Not only will you save money at the pump, the exercise will certainly do you some good

   Make sure the gas cap is on tight. One reason you may not be getting the mileage you expect is because there isn't as much gas in your tank as you think. 147 million gallons of gas were lost last year due to evaporation. Why did it evaporate? The gas cap was not on tight. So just make sure it is tight, and it will enable you to keep all the gas you pay for

   Avoid idling. When you do need to drive your car, make sure you avoid idling whenever possible. When your car is running, but not moving, your gas mileage is absolute zero. So if your car will remain stationary for more than a minute or so, switch the engine off. However, only do this when it is safe to do so

   Accelerate and break steadily. While driving, always apply steady and consistent pressure to your car's accelerator pedal. A heavy foot will always result in reduced gas mileage and poor fuel consumption

   Drive the speed limit. Always try to drive at or near the speed limit. The optimal traveling speed for every make and model vehicle is different. However, the faster you drive, the worse your gas mileage and fuel consumption will be. Drive as fast as you need to in order to maintain a safe driving speed. But, save highway driving speeds for the highway and not around town

   Coast when possible. Constantly accelerating and braking only wastes fuel and reduces your car's fuel consumption. So, whenever possible, coast and avoid burning excess fuel. This takes a little practice, but can be a great way to increase the fuel economy of your vehicle

   Use cruise control on the highways. Cruise control means that your car will be going at a constant velocity, which means there is no acceleration. No acceleration reduces the amount of work your engine does, and therefore it uses less gas. You should set your cruise control at the speed limit, because 55 miles per hour is the perfect speed for maximum fuel efficiency

   Make your car more aerodynamic. You can do so by removing the roof racks on top of the car, and also by decreasing the weight of the car by taking out unneeded items

   Keep the windows closed. The more aerodynamic your vehicle remains, the better your car's fuel efficiency. Keeping your windows down while driving creates more drag and wind resistance for your automobile. If you are driving at speeds of less than 35 mph, it is usually okay to keep the windows down. However, at higher speeds, you should keep the windows up order to reduce drag and improve fuel consumption

   Minimize air conditioning. There will be times, of course, when summer heat will cause you to use the air conditioning system. However, use the AC in moderation. If you need to choose between keeping your windows rolled down or using the AC at high speeds, use the air conditioning on a low setting

   Replace dirty air filters. Dirty air filters cause your car's engine to work much harder than it has to and always results in poor fuel economy. So, make sure you follow the manufacturer's recommendation for periodically changing out the air filter. A clean air filter allows your engine to perform more efficiently and also helps you save money at the pump

   Maintain proper tire inflation. Check your car owner's manual and always ensure your tires are inflated to the proper air pressure level. Improperly inflated tires can reduce your car's fuel economy by up to five percent in some cases. This is quite simply a complete waste of fuel and money

   Reduce weight in the vehicle. Get rid of any unnecessary items in your car's trunk or other areas of the vehicle. For every 100 pounds of weight in the vehicle, your car's fuel economy decreases by about one or two percent. By making sure your vehicle remains as light as possible, you can improve the fuel consumption of your vehicle and save money on your fuel bill

Answer:

The flame test is important in these fields as it helps scientists in determining the metal ions present in elements under study from their emission spectrum.

Explanation:

The Flame test is an important test in Chemistry that is based on the fact that metal ions emit certain characteristic spectrum. The element under investigation is made to pass through a hot, non-luminous flame. The resulting spectrum emitted determines the present metal ions. It is important in;

1. Forensics: Forensic is the application of scientific methods in detecting crime. If for example, a food substance is poisoned, the flame test can help in determining the metal ions present in the food and to know if they are indeed poisonous.

2. Astronomy: Scientists observe the stars and the spectra emitted by them to know which elements have the same colors. This also helps them to know how many light years away the stars are.

3. Environmental and Industry issues: Some industries may be fund guilty of releasing substances such as in oil exploration or bad water to the environment. Flame tests would help to determine which metal ions are present in these substances and their potential for and degree of harm.

Answer:

A) Boiling points

B) Melting points

D) Phase (solid, liquid, gas) at room temperature

Explanation:

Intermolecular forces are attractive forces between molecules. Generally, intermolecular forces are much weaker than intramolecular forces.

All substances exist in one of three states: gas, liquid, or solid. The major difference between the condensed state and the gaseous state is the distance separating molecules.

The boiling points of substances often reflect the strength of the intermolecular forces operating among the molecules. At the boiling point, enough energy must be supplied to overcome the attractive forces among molecules before they can enter the vapor phase. If it takes more energy to separate molecules of substance A than of substance B because A molecules are held together by stronger intermolecular forces, then the boiling point of A is higher than that of B. The same principle applies also to the melting points of the substances. In general, the melting points of substances increase with the strength of the intermolecular forces.

d) There is a direct relationship: as thermal energy increases, there is less particle movement.

The correct option is C.

There is a direct relationship: as thermal energy increases, there is more particle movement.*****

Explanation:

There is a direct relationship: as thermal energy increases, there is more particle movement because when there is increase in thermal energy or heat in a substance, the particles start to vibrate and move faster as a result of the particles gaining kinetic energy which is as a result of increased collision and diffussion rates.

As they vibrate the space between the particles increases which result in increase in motion or movement of the particle
