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.

What heat transfer happens when you burn your hand by touching a fire?

• Radiation

• Conduction

• Convectio

• I don't know!!!!!!!!!!!

Why does food wrapped in aluminum foil keep warm for a long time?

• Aluminum foil is an insulator and prevents heat loss by conduction.

• Aluminum foil forms an air-tight seal and prevents heat loss by convection.

• The silver surface of the foil reflects heat in and prevents heat loss by radiation.

• The silver surface of the foil absorbs heat from the surroundings and keeps the food warm.
