Thermal Energy Transfer

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 are the three types of heat transfer?

Back

The three types of heat transfer are conduction, convection, and radiation.

Front

Define conduction.

Back

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

Front

Define convection.

Back

Convection is the transfer of heat through the movement of fluids (liquids and gases) due to differences in temperature.

Front

Define radiation.

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as sunlight.

Front

What are convection currents?

Back

Convection currents are the circular movements of fluid caused by the rising of warmer, less dense fluid and the sinking of cooler, denser fluid.

Front

How does temperature differ from heat?

Back

Temperature measures the average kinetic energy of particles, while heat is the energy transferred between objects due to a temperature difference.

Front

What is an example of conduction?

Back

Touching hot sand with your feet is an example of conduction.

Front

What is an example of convection?

Back

The movement of warm air rising and cool air sinking in a room is an example of convection.

Front

What is an example of radiation?

Back

The Sun heating the Earth is an example of radiation.
