Thermal Energy Transfer

Front

What is thermal energy transfer?

Back

The process of heat moving from one object or substance to another due to a temperature difference.

Front

What is conduction?

Back

The transfer of heat through direct contact between materials, where heat moves from the hotter object to the cooler one.

Front

What is convection?

Back

The transfer of heat in fluids (liquids and gases) through the movement of the fluid itself, where warm fluid rises and cool fluid sinks.

Front

What is radiation?

Back

The transfer of energy through electromagnetic waves, which can occur in a vacuum, such as the heat from the sun reaching the Earth.

Front

What is an example of conduction?

Back

A metal spoon getting hot when placed in a pot of boiling water.

Front

What is an example of convection?

Back

Warm air rising and cool air sinking in a room, creating a circulation of air.

Front

What is an example of radiation?

Back

Feeling warmth from the sun on your skin.

Front

What type of heat transfer occurs in solids?

Back

Conduction.

Front

What type of heat transfer occurs in liquids and gases?

Back

Convection.

Front

What is thermal equilibrium?

Back

The state in which two objects in contact reach the same temperature and no heat flows between them.
