Considering that convection is driven by differences in temperature, double-pane windows are most likely used to 

• create a convection current from the outside air to the inside air.

• increase the rate of heat flow to the outside air 2

• create a convection current from the inside air to the outside air.

• decrease the rate of heat flow to the outside air.

During a heat transfer demonstration, students observed water being pumped around a closed loop in an engine. The moving water carries heat from the hot engine to the radiator. Which type of heat transfer is involved when the cooler water absorbs heat while in contact with the hot engine?

• Convection

• Conduction

• Insulation

• Radiation

The transfer of heat by currents through liquids of gases is called

• Perspiration

• Radiation

• Conduction

• Convection

What is the definition of CONVECTION

• When heat transfers through waves.

• When heat transfers from objects that are touching.

• a  hot liquid or air that  expands, becomes less dense, and rises or becomes more dense, and sinks.

• Heat traveling from the sun

This is a lava lamp. When the light bulb heats the wax, the wax rises. When the wax cools, it falls. This cycle of rising/falling is an example of:

• Conduction.

• Convection.

• Radiation.
