Conduction Convection and Radiation

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 sunlight, which can travel through a vacuum.

Front

How does heat transfer occur between two objects?

Back

Heat always flows from the hotter object to the colder object until thermal equilibrium is reached.

Front

What is an example of conduction?

Back

An ice cube melting in a person's hand is an example of conduction.

What is an example of convection?

Back

A furnace heating the air in a school is an example of convection.

What is an example of radiation?

Back

The sun shining down on a family playing on the beach is an example of radiation.

Front

What happens to the temperature of an object when it absorbs heat?

Back

The temperature of the object increases when it absorbs heat.

Front

What happens to the temperature of an object when it loses heat?

Back

The temperature of the object decreases when it loses heat.

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects in contact with each other reach the same temperature and no heat flows between them.
