What is the definition of CONDUCTION?

• When heat is transferred from objects like rays of light or electromagnetically.
• a  hot liquid or air that  expands, becomes less dense, and rises or becomes more dense, and sinks.
• When heat transfers from objects that are touching.
• When heat transfers through the heater or AC in your house.

• Radiation

• Conduction

• Convection

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.

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

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