Thermal Energy

What are the temperature scales used in science?

• Celcius

• Kelvin

• Fahrenheit

• Degrees

True or false. The size of an object or the amount of a substance does affect the temperature.

• True

• False

What is the definition of heat?

• The measure of the average kinetic energy of the particles of an object/substance.

• The flow of energy from warmer places to cooler places due to difference in temperatyre.

• The transfer of heat in a fluid caused when hotter fluids rise and cooler fluids sink.

• The transfer of heat through empty space

Thermal equilibrium is when...

• Heat flows from a cooler object to a hotter object until they have an equal temperature.

• When two objects have different temperatures.

• Heat flows from a hotter object to a cooler object until they have an equal temperature.

What is an example of conduction?

• A house's attic is always warmer than its basement

• The sun's energy reaches Earth from millions of miles away

• The ocean circulates around the Earth as cool water sinks and pushes warm water out of the way

• Your computer leaves the desk feeling very hot after you've been using it for a while

What is an example of convection?

• A house's attic is always warmer than its basement

• The sun's energy reaches Earth from millions of miles away

• The ocean circulates around the Earth as cool water sinks and pushes warm water out of the way

• Your computer leaves the desk feeling very hot after you've been using it for a while

What is an example of radiation?

• A house's attic is always warmer than its basement

• The sun's energy reaches Earth from millions of miles away

• The ocean circulates around the Earth as cool water sinks and pushes warm water out of the way

• Your computer leaves the desk feeling very hot after you've been using it for a while

What is an insulator?

• Materials that allow heat energy to move through them easily.

• Materials that do not allow heat energy to move through them easily.

What is kinetic energy?

• The stored energy of an object

• The energy an object has because of motion

What is the temperature that water boils at in CELCIUS?
