Write a scientific explanation of conduction.
Answer:
Conduction is the process by which heat energy is transmitted through collisions between neighboring atoms or molecules.
Explanation:
These vibrating molecules collide with their neighboring molecules, making them also vibrate faster. As these molecules collide, thermal energy is transferred via conduction to the rest of the pan.

How do water, wind, and thermal energy from the sun move about the earth's surface?
Molecules move more quickly because the sun's light energy transforms into heat energy on the planet. While cooler polar air and water travel away from the poles and towards the equator, warm air and water molecules rise and move in the opposite direction.
What is light energy ?The capacity to make different forms of light visible to human sight makes light energy a sort of kinetic energy. Light is referred to as an electromagnetic radiation that is produced by hot things like the sun, lasers, and lightbulbs. Photons, which are tiny energy packets, are present in light.
Water temperature, biological activities and plant photosynthesis and development are all impacted by light energy.
The air is heated by the sun, and warm air rises. The colder air from the surroundings is forced to enter to replace the rising heated air. The result of this is the wind. Ocean currents function similarly.
Thus, Molecules move more quickly because the sun's light energy transforms into heat energy on the planet.

How is a lunar eclipse similar to a solar eclipse? How are they different?
Answer:
they moon and sun are a factor in both of them
Explanation:
Answer:
From our perspective on Earth, two types of eclipses occur: lunar, the blocking of the Moon by Earth's shadow, and solar, the obstruction of the Sun by the Moon. When the Moon passes between Sun and Earth, the lunar shadow is seen as a solar eclipse on Earth. Also they are similar by An eclipse occurs when one celestial object obscures another celestial object. In the case of a solar eclipse, the moon moves between the Earth and the sun, thus obscuring the sun. A lunar eclipse occurs when the Earth moves directly between the sun and the moon. Either type of eclipse can be total or partial.

To clean their drain pipes, some people make a solution of baking soda and vinegar. Baking soda, also known as sodium bicarbonate (NaHCO3), reacts with acetic acid (C2H4O2) in vinegar. When these substances combine, the solution becomes colder, and sodium acetate (NaC2H3O2), water (H2O), and carbon dioxide gas (CO2) form. The gas creates bubbles that help clean the inside of the pipes. is this reaction endothermic or exothermic?

Defining Emotional Appeal
An emotional appeal is used to sway the emotions of an audience to make them support the speaker’s argument.
LEARNING OBJECTIVES
Break down the components that make up an emotional appeal
KEY TAKEAWAYS
Key Points
Pathos represents an appeal to the emotions of an audience.
An emotional appeal uses the manipulation of the emotions rather than valid logic to win an argument.
Emotional appeal is a logical fallacy, whereby a debater attempts to win an argument by trying to get an emotional reaction from the opponent and audience.
In debating terms, emotional appeals are often effective as a rhetorical device, but are generally considered naive or dishonest as a logical argument, since they often appeal to the prejudices of listeners rather than offer a sober assessment of a situation.
Key Terms
logical fallacy: A fallacy; a clearly defined error in reasoning used to support or refute an argument, excluding simple unintended mistakes.
Emotional Appeal Defined
Pathos represents an appeal to the audience’s emotions. Pathos is a communication technique used most often in rhetoric (where it is considered one of the three modes of persuasion, alongside ethos and logos), and in literature, film, and other narrative art.
Emotional appeal can be accomplished in a multitude of ways:
By a metaphor or storytelling, common as a hook
By a general passion in the delivery
By an overall emotion
By the sympathies of the speech or writing as determined by the audience
The pathos of a speech or writing is only ultimately determined by the audience.
The Purpose of an Emotional Appeal
An emotional appeal is directed to sway an audience member’s emotions and uses the manipulation of the recipient’s emotions rather than valid logic to win an argument. An emotional appeal uses emotions as the basis of an argument’s position without factual evidence that logically supports the major ideas endorsed by the presenter. In an emotional appeal, persuasive language is used to develop the foundation of an appeal to emotion-based arguments instead of facts. Therefore, the validity of the premises that establish such an argument does not prove to be verifiable.
A US soldier holds his daughter and his son.
Emotional Appeal: A picture like this could be used as an emotional appeal for a charity campaign to increase funding for soldiers’ families.
Emotional appeal is a logical fallacy, whereby a debater attempts to win an argument by trying to get an emotional reaction from the opponent and audience. It is generally characterized by the use of loaded language and concepts (God, country, and apple pie being good concepts; drugs and crime being bad ones). In debating terms, emotional appeals are often effective as a rhetorical device, but are generally considered naive or dishonest as a logical argument, since they often appeal to the prejudices of listeners
