Thermal Energy - 4th

Front

What is thermal energy?

Back

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

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 sunlight.

Front

What is thermal expansion?

Back

Thermal expansion is the increase in volume of a substance as its temperature increases.

Front

What is thermal contraction?

Back

Thermal contraction is the decrease in volume of a substance as its temperature decreases.

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects in contact do not exchange heat, meaning they are at the same temperature.

What is an example of conduction?

Back

A metal spoon getting hot from a boiling pot.
