Glossary Terms
Heat
Molecular motion
What is differential heating?
Different materials heat up at different rates
What produces the most radiant energy?
the sun
What word is in the word conduction?
Conduct
What date did winter begin?
Dec 21
What is energy transfer that occurs between molecules when they come into contact?
Conduction
The sun radiates a certain amount of energy, and it is received by soil and water. Do they absorb the same or different amounts of energy?
The same
What is radiation?
Energy transfer at a distance without direct contact
Which metal was the strongest conductor in the pasta video? How could you tell?
Aluminum - the pasta fell off first
How many students in 6M have birthdays in December?
3
What is radiant energy?
Energy from the sun that travels through space
Which heats up faster, soil or water?
Soil
Give an example of something that radiates energy
Many possible answers
Explain how conduction is involved in warming your hands against a warm teapot
The molecules of the teapot touch the molecules in your hands - energy transferred to skin molecules - energy transferred to other hand molecules
How many classes are there at School 3?
24
When hot matter does this, it cools down
Reradiates
Which earth material stores the least heat?
Air
What is reradiation?
When a hot material/object releases heat energy back into the atmosphere
Explain the process how heat is conducted when you boil a pot of water
Heat from fire radiates to pot - metal heats up - metal heats other metal molecules - water heats up - water heats other water molecules until all water is heated
What are Ms. Motola's siblings names?
Kyra and Jack
This is the main kind of energy from the sun that heats the earth
Visible light
Which earth material stores the most heat?
Water
What happens when radiant energy strikes an atom or molecule?
The atom/molecule absorbs the energy and begins moving, molecular motion = heat so it heats up - this may also lead to conduction as it conducts energy to the molecules touching it
Explain how conduction is related to the heating of the atmosphere
Radiant energy heats the earth's surface - surface conducts heat to air molecules touching the surface - air molecules conduct heat to other air molecules, etc.
When you graph information in a line graph, on which axis should you put the dependent variable? (dependent variable = thing that changes, such as temperature)
y axis
