Heat Transfer

Front

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 are the three main methods of heat transfer?

Back

The three main methods of heat transfer are conduction, convection, and radiation.

Front

Define conduction.

Back

Conduction is the transfer of heat through a solid material without the movement of the material itself.

Front

Define convection.

Back

Convection is the transfer of heat through fluids (liquids and gases) by the movement of the fluid itself.

Front

Define radiation.

Back

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

Front

What happens to particles when heat is added?

Back

When heat is added, the particles gain energy and move faster.

Front

What happens to particles when heat is removed?

Back

When heat is removed, the particles lose energy and move slower.

Front

In which direction does heat flow?

Back

Heat flows from areas of high temperature to areas of low temperature.

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects reach the same temperature and no heat flows between them.

Front

What is an example of conduction?

Back

An example of conduction is a metal spoon getting hot when placed in a pot of boiling water.
