Thermal Energy, Temperature, and Heat Notes

Thermal energy is what?

The motion of particles

What is temperature?

A measurement of thermal energy

What is heat?

The transfer of thermal energy

Total energy is ________ and _________

size, mass

_________ = _________ (TE)

temperature, total energy

Thermal energy - _________ amount of ALL _____________ in a system.

the total, of the energy

Cold objects still have ________ ________! Thermal energy DOES depend on __________ (_______) of the _________ (_________) of an object.

thermal energy, mass, (matter), size, (volume)

Temperature - ________ kinetic energy of a system. Does not _______ on the ________ or the ________ of the object.

Averages, depend, mass, volume

Heat - transfer of ______ kinetic energy to ________ kinetic energy.

higher, lower

HEAT MOVES FROM _________ TO __________.

hot, cold

Does the ice cube cool the water, or does the water heat the ice cube? Why?

Water (L) heats the ice cube. This is because heat transfers from hot to cold, so water transfers its energy to the ice cube, causing the ice cube to melt.

__________ = __________ (E,B)

Equilibrium, balance

Relationship between Thermal Energy, Temperature, and Heat - ________ ________ flows from boiling water to the room. As the water loses heat (cools), the molecules move more ________. The pot will continue to cool until it reaches the same ________ (average kinetic energy) as the room. The room is gaining heat. (Room is so big, pot is so small, you probably won’t notice a difference in the room temperature.)

Kinetic energy, slowly, temperature
