Thermal Energy and Heat Transfer

Front

What is the measure of the average kinetic energy of the individual particles in an object?

Back

Temperature

Front

What is the process of heat transfer by convection?

Back

Heat transfer occurs when there is a circulation of hot air/water rising and cold air/water sinking.

Front

What happens to particles in an object as they cool down?

Back

They slow down.

Front

What type of energy is described as the energy of motion?

Back

Kinetic energy.

Front

What is conduction in terms of heat transfer?

Back

Conduction is heat transfer by touch.

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of all the particles in an object.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases).

Front

What is the difference between conduction and convection?

Back

Conduction is heat transfer through direct contact, while convection is heat transfer through fluid movement.

Front

What happens to the temperature of an object when it absorbs heat?

Back

The temperature of the object increases.

Front

What is the role of particles in heat transfer?

Back

Particles transfer energy through collisions and movement.
