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 is conduction?

Back

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

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 and density.

Front

What is radiation?

Back

Radiation is the transfer of thermal energy through electromagnetic waves, which can occur in a vacuum.

Front

How does thermal energy transfer occur in solids?

Back

In solids, thermal energy transfer occurs primarily through conduction.

Front

How does thermal energy transfer occur in fluids?

Back

In fluids, thermal energy transfer occurs through convection.

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 happens to thermal energy when ice melts?

Back

When ice melts, thermal energy is absorbed from the surroundings, causing the ice to change from solid to liquid.

Front

What is an example of conduction in everyday life?

Back

An example of conduction is touching a hot stove and feeling the heat transfer to your hand.

Front

What is an example of convection in everyday life?

Back

An example of convection is the warm air rising from a heater and circulating in a room.
