Thermal Energy & Transforming Energy

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 conduction?

Back

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

Front

What is convection?

Back

Convection is the transfer of thermal energy through the movement of fluids (liquids or gases) caused by differences in temperature.

Front

What is radiation?

Back

Radiation is the transfer of energy through electromagnetic waves, such as light or heat, without the need for a medium.

What happens to energy in a flashlight when it is turned on?

Back

The battery's chemical energy is transformed into electrical energy, which is then converted into light energy and thermal energy.

Front

What are the two forms of energy released when wood burns in a fireplace?

Back

Light energy and thermal energy.

Front

How does insulation work in a home?

Back

Insulation slows the transfer of thermal energy, helping to keep homes warm in winter and cool in summer.

Front

What is the role of air in fiberglass insulation?

Back

Air trapped in fiberglass insulation acts as a good insulator, slowing the transfer of energy.

Front

How does heat affect a colder object in warmer air?

Back

Heat causes the thermal energy of the colder object to increase as energy moves from the warmer air to the colder object.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state.
