Understanding Thermal Energy Basics

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 an object.

Front

What is a common source of thermal energy?

Back

The Sun is a common source of thermal energy.

Front

What is conduction?

Back

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

Front

What happens to an object's thermal energy when its temperature rises?

Back

The thermal energy of the object increases.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases).

Front

What is radiation in terms of heat transfer?

Back

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

Front

Which method of heat transfer does NOT involve matter?

Back

Radiation does not involve matter; it can occur in a vacuum.

Front

What is insulation?

Back

Insulation is a material that reduces the transfer of heat.

Front

What is an example of a thermal energy source?

Back

A campfire is an example of a thermal energy source.

Front

What is the effect of heat on the particles of a substance?

Back

Heat causes the particles of a substance to move faster.
