Heat and Temperature

Front

What is heat?

Back

Heat is a form of energy that is transferred between objects due to a temperature difference.

Front

What is temperature?

Back

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

Front

What is thermal energy?

Back

Thermal energy is the total energy of all the particles in a substance, including both kinetic and potential energy.

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

How does heat transfer occur?

Back

Heat transfer occurs from areas of high temperature to areas of low temperature.

Front

What happens to the thermal energy of water when its temperature increases?

Back

The thermal energy of water increases as its temperature increases.

Front

What is an example of heat transfer by radiation?

Back

Feeling warmth when you sit in a sunny place is an example of heat transfer by radiation.
