Thermal Energy & Transforming Energy

Front

What is thermal energy?

Back

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

Front

How can thermal energy be increased in a substance?

Back

By increasing the temperature of the substance.

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 conduction?

Back

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

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.

Front

What is potential energy?

Back

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

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object due to its motion.

Front

How does energy transfer occur in a heating system?

Back

Energy transfer occurs through convection, as warm air rises and cool air sinks.

Front

What happens to potential energy when fuel burns in a rocket?

Back

The potential energy is converted into kinetic energy, thermal energy, light, and sound energy.

Front

What is an example of energy transfer through conduction?

Back

Feeling the warmth of the bricks around a fireplace by touching them with your hand.
