What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials, where heat moves from the hotter object to the cooler one.

What is convection?

Back

Convection is the transfer of heat in fluids (liquids and gases) through the movement of the fluid itself, caused by differences in temperature and density.

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, which can occur in a vacuum and does not require matter.

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects in contact with each other reach the same temperature, resulting in no net heat transfer between them.

What happens to air in a hot air balloon when heated?

Back

When the air inside a hot air balloon is heated, it expands and becomes less dense than the cooler air outside, causing the balloon to rise.

What is thermal expansion?

Back

Thermal expansion is the increase in volume of a substance as its temperature increases, due to the increased movement of its particles.

What is thermal contraction?

Back

Thermal contraction is the decrease in volume of a substance as its temperature decreases, due to the decreased movement of its particles.

What is an example of heat transfer by conduction?

Back

An example of heat transfer by conduction is a metal spoon getting hot when placed in a hot soup.

What is an example of heat transfer by convection?

Back

An example of heat transfer by convection is warm air rising and cool air sinking in a room heated by a radiator.
