Front

What is conduction?

Back

A method of heat transfer that occurs when objects touch each other.

Front

What is convection?

Back

A method of heat transfer that occurs in fluids (liquids and gases) where warm air or liquid rises and cool air or liquid sinks.

Front

What is radiation?

Back

A method of thermal energy transfer that moves through empty space without needing a medium.

Front

What is temperature?

Back

A measure of the average kinetic energy of the particles in a sample of matter.

Front

What is specific heat?

Back

The amount of heat required to raise the temperature of one gram of a substance by one degree Celsius.

Front

How does warm air behave in convection?

Back

Warm air rises because it is less dense than cool air.

Front

What happens to cool air in convection?

Back

Cool air sinks because it is denser than warm air.

Front

Give an example of conduction.

Back

Touching a hot stove and feeling the heat transfer to your hand.

Front

Give an example of convection.

Back

The attic is warmer than the basement due to the rising warm air.
