Unit 5: Thermal Energy Review

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 are the three types of thermal energy transfer?

Back

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

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 and gases) caused by differences in temperature.

Front

What is radiation?

Back

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

Front

What happens to thermal energy when ice melts?

Back

When ice melts, it absorbs thermal energy from its surroundings, causing the temperature of the surroundings to decrease.

Front

How does thermal energy move between a hot object and a cold object?

Back

Thermal energy moves from the hot object to the cold object until both reach the same temperature.

Front

What is energy transfer?

Back

Energy transfer is the movement of energy from one object or substance to another.

Front

What is the law of conservation of energy?

Back

The law of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What is an example of convection in everyday life?

Back

An example of convection is the way warm air rises and cool air sinks in a room, creating a circulation of air.
