energy transferred between objects at different temperatures
average kinetic energy of the particles that make up a substance
How does heat affect the thermal energy of an object that is colder than the air that surrounds it?
Heat decreases the thermal energy of an object as energy moves to the air.
Heat causes the thermal energy of the object to increase as energy moves from the warmer air to the colder object.
Heat has no effect on thermal energy, but it increases the potential energy of an object.
Heat is not related to thermal energy, so it cannot affect the thermal energy of an object.
Kito puts his spoon into a helping of fresh, hot, mashed potatoes as shown in the picture. Which process takes place when the objects come together?
The temperature of the spoon increases, but its thermal energy does not change.
Energy in the form of heat is transferred by conduction from the warmer mashed potatoes to the cooler spoon.
The thermal energy of both the mashed potates and the spoon increase as the energy in the form of heat is transferred between them.
The average temperature of the spoon does not change.
As energy in the form of heat is added to an ice cube, it begins to melt. What causes melting.
Heat causes the molecules to expanded and forces them apart.
Heat removes thermal energy from the ice cube and causes it to become liquid water.
Adding energy causes the bonds between the hydrogen and oxygen in the ice cube to break.
The transfer of thermal energy to the ice cube causes its molecules to move faster.

Alex noticed that a metal door that sticks on hot days does not stick when it cools off at night. This is because the metal contracts as it cools. The reason for this is that, as the metal cools, the particles:
become smaller and take up less space
slow down and move closer together
merge together to form fewer particles
speed up and move farther apart
