Review-Thermodynamics

Which of the following occurs by way of Radiation?

• The sun warming up your face.
• A bunsen burner heating up a beaker.
• A microwave heating up food.
• Your hand heating up a piece of ice.

The air pressure of a tire is higher when it is daytime than at nighttime. This is most likely due to which of the following?

• The tire rolling
• Warm air in the tire producing a decrease in tire volume
• An increase in the speed of the air molecules in the tire
• An increase in the molecular potential energy of the air molecules in the tire

A lava lamp is a decorative item found in some homes. The lamp portion contains a waxy substance in a liquid medium. When the lamp is plugged in, a bulb at the base of the lamp slowly heats the waxy substance sitting at the bottom of the liquid. Eventually, the waxy substance will separate into glob that quickly rise to the top of the lamp where the surrounding liquid cools them and causes them to fall back to the bottom. Based on the information provided, a lava lamp could be used to provide an example of which process of thermal energy transfer?

• Conduction
• Convection
• Radiation
• All of the above
