Thermal Energy & Heat Review

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

What is heat?

Back

Heat is the transfer of thermal energy from one object to another due to a temperature difference.

Front

What is conduction?

Back

Conduction is the process of heat transfer 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 and density.

Front

What is radiation?

Back

Radiation is the transfer of energy through electromagnetic waves, such as light or infrared radiation.

Front

What happens to heat when two objects at different temperatures come into contact?

Back

Heat will flow from the hotter object to the cooler object until thermal equilibrium is reached.

Front

What is an example of conduction?

Back

A metal spoon getting hot in a cup of tea is an example of conduction.

Front

What is an example of convection?

Back

A lava lamp demonstrates convection as the heated wax rises and cools, then sinks.

Front

What is an example of radiation?

Back

Sunlight warming your skin is an example of radiation.

Front

What is the principle of energy conversion?

Back

Energy conversion is the process of changing energy from one form to another, such as chemical energy to thermal energy.
