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

What is conduction?

Back

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

Front

What is convection?

Back

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

Front

What is radiation?

Back

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

How does a metal spoon get warm in hot soup?

Back

The heat from the soup is conducted through the spoon, making the spoon warmer.

Front

What happens to the temperature of water when ice is added?

Back

The temperature of the water decreases because some of the water’s heat is lost to the ice.

Front

Which materials are good conductors of heat?

Back

Metals like copper and aluminum are good conductors of heat.

Front

Which materials are poor conductors of heat?

Back

Materials like plastic and wood are poor conductors of heat.

Front

What is an example of convection in everyday life?

Back

An example of convection is the way warm air rises and cool air sinks in a room.
