Thermal Energy, Heat & Temperature

Front

What is thermal energy?

Back

Thermal energy is the energy that moves particles of matter.

Front

How does heat transfer occur between two objects?

Back

Heat transfer occurs through conduction, convection, or radiation.

Front

What unit is used to measure thermal energy?

Back

The unit used to measure thermal energy is Joules (J).

Front

What happens to the temperature of an object when its particles have more kinetic energy?

Back

The object's temperature is higher.

Front

What is the relationship between temperature and the average kinetic energy of particles?

Back

The temperature of a substance increases as the average kinetic energy of its particles increases.

Front

What is the difference between heat and temperature?

Back

Heat is the energy transferred between objects due to a temperature difference, while temperature is a measure of the average kinetic energy of particles in a substance.

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).

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves.

Front

How does thermal energy affect the state of matter?

Back

Increasing thermal energy can cause a substance to change from solid to liquid (melting) or from liquid to gas (evaporation).
