Unit 4 Review

Front

What is convection?

Back

Convection is the transfer of heat through fluids (liquids and gases) where warmer areas of a liquid or gas rise and cooler areas sink, creating a circulation pattern.

Front

Which example illustrates convection?

Back

The attic is warmer than the basement.

Front

How does heat transfer occur between areas of different temperatures?

Back

Heat transfers from an area of high temperature to an area of low temperature.

Front

What type of heat transfer occurs in solids?

Back

Conduction is the type of heat transfer that takes place in solids.

Front

What happens to particles when more heat is supplied to a system?

Back

The particles would speed up.

Front

What is radiation?

Back

Radiation is the transfer of energy through or by electromagnetic waves.

Front

What is conduction?

Back

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

Front

What is an example of conduction?

Back

Touching a hot metal spoon that has been in a pot of boiling water.

Front

What is the difference between conduction and convection?

Back

Conduction occurs in solids through direct contact, while convection occurs in fluids through the movement of the fluid itself.

Front

What is an example of radiation?

Back

The Sun heating the Earth is an example of radiation.
