Physical Science Review

Which type of energy transfer is demonstrated as hot air rises and cool air falls?

• conduction

• convection

• radiation

• solar

Which statement explains why a stove cools down after being turned off?

• The energy from the stove disappears and does not transfer to the environment

• The environment transfers energy to the stove until the temp is the same.

• The stove transfers energy to the environment until the are the same temperature.

How does convection differ from conduction?

• Conduction is a direct transfer of heat energy, convection is not.

• Convection is a direct transfer of heat energy, while conduction is not.

• Conduction does not require a medium for heat transfer, conduction does.

What most likely occurs when objects of different temperature come into contact?

• Each object conserves its energy, no transfer is made.

• The cooler object transfers energy to the warmer object.

• The warmer object transfers energy to the cooler object.

What is the primary method of heat transfer through solids?

• condensation

• conduction

• convection

• radiation

Which material would most likely be used by electricians to coat the handles of their tools?
