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 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 energy through electromagnetic waves, which can occur in a vacuum.

Front

What is an insulator?

Back

An insulator is a material that does not conduct heat well, preventing heat transfer.

Front

What is an example of conduction in everyday life?

Back

Walking on warm sand with bare feet is an example of conduction.

Front

What happens to heat when it flows into an object?

Back

When heat flows into an object, the change in heat is positive.

Front

What is an example of a good conductor of heat?

Back

Metals, such as copper and aluminum, are good conductors of heat.

Front

What is an example of an insulator used in the kitchen?

Back

An oven mitt is an example of an insulator used in the kitchen.

Front

What is the difference between conduction and convection?

Back

Conduction requires direct contact for heat transfer, while convection involves the movement of fluids.
