temperature
motion
momentum
Heat always moves from ____________ objects to ______________ objects.
cooler, warmer

slower, faster
When two objects are at the same temperature they are in thermal equilibrium
True
False
What is the definition of CONVECTION
When heat transfers through waves.
When heat transfers from objects that are touching.

Which of the following containers of sand has atoms/molecules with the greatest average kinetic energy?
1 kg at 20oC
2 kg at 20oC
4 kg at 20oC
all have the same average kinetic energy
When thermal energy is added to a substance, the substance's particles move:
More rapidly at an increased distance from each other
More rapidly with less distance between each other
More slowly with a greater distance between each other
More slowly with less distance between each other
An object in which molecules are moving faster than another object
has a higher temperature
has a lower temperature
both are in thermal equilibrium
both have the same internal temperature
When would an object left in a room temperature room stop transferring heat?
When it has reached the same temperature as the room temperature air
When it has lost all of its thermal energy
When it has gained all of the air's thermal energy
When it has gained or lost all of its coldness to the air
What is the definition of CONDUCTION?
When heat energy is absorbed or emitted as electromagnetic waves.
when heat causes a hot liquid or gas to expand, become less dense and rise, or becomes more dense, and sink.
When heat transfers from a hotter object to a cooler object through contact
When heat transfers through the heater or AC in your house.
An object's internal energy depends on
The average kinetic energy of all the particles
The total kinetic energy of all the particles
The total kinetic and potential energy of all the particles
The difference between the kinetic and potential energy of the particles
