Thermal Equilibrium

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of the particles in a substance, which is related to its temperature.

Front

True or False: Everything has thermal energy.

Back

True

Front

What happens to the net transfer of heat when two objects have the same temperature?

Back

The net transfer of heat is zero.

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 the speed of molecules in a substance relate to its thermal energy?

Back

The speed of molecules increases with higher thermal energy.

Front

What is an example of conduction?

Back

Ironing a shirt is an example of conduction.

Front

What is an example of convection in a house?

Back

Warm air rising to the attic and cooler air sinking to the basement is an example of convection.

Front

What is the relationship between temperature and thermal energy?

Back

As temperature increases, thermal energy also increases.
