Thermal Equilibrium

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects in contact with each other do not exchange heat, meaning they are at the same temperature.

Front

What is conduction?

Back

Conduction is the transfer of heat through a material without the movement of the material itself, typically occurring in solids.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases) caused by differences in temperature and density.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as infrared radiation, and does not require a medium.

Front

What happens to thermal energy when two objects at different temperatures come into contact?

Back

Thermal energy will flow from the object with a higher temperature to the object with a lower temperature until thermal equilibrium is reached.

Front

What is an example of conduction?

Back

An example of conduction is a metal spoon getting hot when placed in a hot pot of soup.

Front

What is an example of convection?

Back

An example of convection is the warm air rising and cool air sinking in a room, creating a circulation of air.

Front

What is an example of radiation?

Back

An example of radiation is feeling the warmth of the sun on your skin.

Front

What is the direction of heat transfer?

Back

Heat transfers from an area of high temperature to an area of low temperature.

Front

True or False: Everything has thermal energy.

Back

True.
