*7.8A Exploring Thermal Energy Transfer

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter. It is the total kinetic energy of the particles in a substance.

Front

What are the three methods of thermal energy transfer?

Back

The three methods of thermal energy transfer are conduction, convection, and radiation.

Front

Define conduction.

Back

Conduction is the transfer of thermal energy through direct contact between materials.

Front

Define convection.

Back

Convection is the transfer of thermal energy in fluids (liquids and gases) through the movement of the fluid itself.

Front

Define radiation.

Back

Radiation is the transfer of thermal energy through electromagnetic waves, and it does not require a medium.

Front

What is an example of conduction?

Back

An example of conduction is a metal spoon getting hot from a boiling pot of water.

Front

What is an example of convection?

Back

An example of convection is warm air rising to the ceiling in a room.

Front

What is an example of radiation?

Back

An example of radiation is the sun heating the Earth.

Front

How does thermal energy transfer occur in solids?

Back

Thermal energy transfer in solids occurs primarily through conduction.

Front

How does thermal energy transfer occur in liquids and gases?

Back

Thermal energy transfer in liquids and gases occurs primarily through convection.
