Unit 4 Review

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.

The attic is warmer than the basement.

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

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

The particles would speed up.

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

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

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

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

The Sun heating the Earth is an example of radiation.
