Thermal Energy

Front

What is thermal energy?

Back

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

Front

What are the three types of heat transfer?

Back

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).

Front

Define radiation.

Back

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

Front

What is an insulator?

Back

An insulator is a material that does not conduct heat well, preventing heat transfer.

Front

Give an example of a good thermal insulator.

Back

Styrofoam is a good thermal insulator.

Front

What happens to particles in a substance when it is heated?

Back

The particles gain kinetic energy and move faster.

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects in contact do not exchange heat, meaning they are at the same temperature.

Front

How does heat transfer occur in solids?

Back

Heat transfer in solids occurs mainly through conduction.
