Which of the following is true about the picture above? What would it be?
Answer:
Container A is a solution and Container B is a colloid.
Explanation:
Container A is a solution as the tyndall efffect is not present. You cannot see the light bean through the glass.
Container B is a suspension or a colloid as you can see the beam through the glass.
The first option proposes Container A is a colloid...this is not correct
The third option is not true as the tyndall effect is only displayed in container B
The fourth option is not correct the tyndall effect is not present in container A meaning it would not be a suspension or a colloid and you can see the tyndall effect in container B indicating its not a solution

3. Scott and James work at a grocery store. After the grocery store closed, they were playing a game with a shopping cart and Scott’s skateboard. They crashed the skateboard and the shopping cart two times. The shopping cart had more mass in Crash 2 than it did in Crash 1. Use the information in the diagram to answer.
In which crash did the skateboard experience a stronger force? Why?
Answer: B) Crash 2; the force on the cart was stronger in this crash, so the force on the skateboard was also stronger.
Explanation:
Skateboards are subjected or experience to a greater force in Crash 2.
The force applied on the cart 2 was stronger or powerful in this collision 2, thus the force or power on the skateboarding was also higher and greater, according to the statement.
Strong forces usually do more damage to specific items or things.

A physical change is easier / more difficult to reverse than a chemical change.
Answer:
the answer is that a physical change is easier to reverse then a chemical change.
Explanation: In order for a physical change to take place it's easier to just undo what happened then if it was a chemical change because in order for very few chemical changes to reverse to it's original substance you would need another chemical change.

What are different states of matter?The matter is anything that has mass and occupies space.
Matter can exist in four different states: solid, liquid, gas, and plasma.
By examining the arrangement of molecules, it is possible to comprehend the characteristics of the many forms of matter.
The state of a solid turns to a liquid when it is heated past its melting point.
A liquid turns into a gas when it is heated past the point at which it vaporizes.
Solids have a distinct shape and dimension and are densely packed.
Liquids fill the container's space and are loosely packed.
Gas has a large intermolecular distance and is not stiff.
When energy is removed from the particles of a liquid, the speed gets slowed, and so the motion decreases, as the motion is limited they become packed and the distance between them decreases, and the intermolecular forces increases.

Which event is part of a convection current in the air?
A. Cool air sinks.
B. Cool air rises.
C. Warm air swirls.
D. Warm air sinks
Answer:
The answer is (Cool air sinks)
Explanation:
hope I help
The Cool air sinks are the part of a convection current in the air. Therefore, option A is correct.
What is convection current ?Convection currents are a type of natural heat transfer that involves the transfer of energy and heat from one location to another. We can use the sensation of heat when placing our hands over a campfire as an example of this. Convection currents are to blame for this.
Convection is a method of heat transfer in which gases or liquids are moved between areas of varying temperatures. Natural or free convection is the term used to describe convection that occurs naturally.
Convection currents move heat from one place to another by using the mass motion of a fluid, such as water, air, or molten rock. Convection currents' ability to transfer heat is what drives ocean currents, atmospheric weather, and geology.
Thus, option A is correct.

Which element is this.Its shiny,Is solid at room temperature, has atoms with two valence electrons?A:Lithium B:Strontium C:Aluminium D:Silicon
Answer:
Strontium
Explanation:
STRONTIUM
Strontium is a chemical element that is non radioactive and its occur naturally. It is a shiny and silvery white metal that have atomic number of 38 and it belong to group 2 member of the periodic table which is why it have two valence electrons. It is a solid metal at room temperature.
About 99% of Strontium is found in bones. It help to make new bones in humans by replacing the old bones.
Therefore, it is strontium.
Strontium is the element which is shiny, solid at room temperature and has two electrons in its outermost shell.
The atomic number of Strontium is 38. In the first shell, there are two electrons, in the second and fourth shell has space for 8 electrons so these shells are filled with electron whereas third shell has 18 electrons and the fifth shell has 2 electrons. Strontium belongs to second group i.e. alkaline earth metals due to which it has two valance electrons in its outermost shell.

D both the energy and molecules are trapped in the system.
Answer:
A) Energy and Water molecules are free to escape into the surrounding environment.
Explanation:
Hello! This is the correct answer! (I took the K12 test)
I hope this helps! Have a blessed day! :)
When boiling a pot of water on the stove without a lid on the pot, the energy and water molecules are free to escape into the surrounding environment.
What is boiling?Boiling point of a substance is the temperature at which the substance changes from liquid state to gaseous state where these two systems comes in equilibrium.
Thus when a liquid is boiled, the liquid molecules get more energy to move apart and they escape into gaseous state. With change in state of the substance, the energy also be transferred from the liquid to the environment.
If the pot is closed with a lid, then both energy can be transferred but molecules get trapped inside. But here the pot is open and thus the gas molecules and energy are free to move outside.
Therefore, option A is correct for the boiling of water in an open pot.
