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 is related to its temperature.

Front

What is heat transfer?

Back

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

Front

What are the three methods of heat transfer?

Back

The three methods 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 and density.

Front

What is radiation?

Back

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

Front

What is the boiling point?

Back

The boiling point is the temperature at which a liquid changes to a gas.

Front

What is the melting point?

Back

The melting point is the temperature at which a solid changes to a liquid.

Front

What is matter?

Back

Matter is anything that has mass and takes up space.

Front

What is temperature?

Back

Temperature is a measure of the average kinetic energy of the particles in an object.
