What is heat transfer?

Back

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

Front

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.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases), where warmer parts rise and cooler parts sink.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as infrared radiation, without the need for a medium.

Front

Why is brick a good material for fireplaces?

Back

Brick is heat resistant, meaning it can withstand high temperatures without melting or deforming.

Front

What happens to heat when it moves from high to low temperature?

Back

Heat naturally flows from areas of higher temperature to areas of lower temperature until thermal equilibrium is reached.

Front

What is an insulator?

Back

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

Front

What is a conductor?

Back

A conductor is a material that allows heat to pass through it easily, facilitating heat transfer.

Front

How does walking on warm sand demonstrate conduction?

Back

Walking on warm sand shows conduction because heat is transferred from the hot sand to your cooler feet through direct contact.

Front

What is the role of poor conductors in insulation?

Back

Poor conductors are used in insulation materials to reduce heat transfer, keeping heat in or out of an area.
