On the short side of the paper, fold it down an inch.. 2. Now fold it in half, hamburger style.. 3. Now fold it in 1/3.. Conduction. Convection . Radiation. Heat Transfer. Examples. Conduction Convection . Radiation. Types of Heat transfer. Heat Transfer. Heat can be transferred in 3 ways. Conduction. Convection. Radiation. Heat flow depends on the temperature difference – . flows from hot to cold. Heat Transfer. Heat always moves from a warmer place to a cooler place.. Hot objects in a cooler room will cool to room temperature.. Cold objects in a warmer room will heat up to room temperature.. Question.
