Thermal Energy and Heat Transfer

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of all the particles in an object, which determines its temperature.

Front

What is heat transfer?

Back

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

Front

What are the three types of heat transfer?

Back

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

Front

What is conduction?

Back

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

Front

What is convection?

Back

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

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as light.

Front

In which state of matter do particles have the most kinetic energy?

Back

Gas.

Front

How does heat flow between objects?

Back

Heat flows from an area of higher temperature to an area of lower temperature.

Front

What is an example of conduction?

Back

Touching a hot stove and feeling the heat transfer to your hand.

Front

What is an example of convection?

Back

Boiling water where hot water rises and cooler water sinks, creating a current.
