Heat and Heat Transfer

Front

What is heat?

Back

Heat is a form of energy that is transferred between objects due to a temperature difference.

Front

What is an insulator?

Back

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

Front

Which material is NOT a good insulator?

Back

Metal is NOT a good insulator.

Front

What is thermal expansion?

Back

Thermal expansion is the increase in volume of a substance when it is heated.

Front

What happens to molecules in a gas or liquid when they are heated?

Back

They spread out, become less dense, and rise.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases).

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as sunlight.

Front

What is specific heat?

Back

Specific heat is the amount of energy needed to change the temperature of 1 kg of a substance by 1 degree Celsius.

Front

What is thermal conductivity?

Back

Thermal conductivity is a measure of how well a material conducts heat.
