Heat, Thermal Energy, and Temperature

Front

What is heat?

Back

Heat is the transfer of thermal energy from one object to another due to a temperature difference.

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of the particles in an object, which is related to its temperature.

Front

What is temperature?

Back

Temperature is a measure of the average kinetic energy of the particles in a substance.

Front

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

Back

Heat will flow from the warmer object to the cooler one until they reach the same temperature.

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials.

Front

What is convection?

Back

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

Front

What is radiation?

Back

Radiation is the transfer of energy by electromagnetic waves, which can occur in a vacuum.

Front

What is an example of conduction?

Back

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

Front

What is an example of convection?

Back

An example of convection is warm air rising and cool air sinking in a room.

Front

What is an example of radiation?

Back

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