How to Create Heat Transfers
- 1). Place a heated object so that is directly touching an unheated object. This is heat transfer through conduction, and it is the simplest form. One of the most accessible examples is when you put a pan on the stove. The pan (and the food in it) heats through conduction, or the direct transfer of heat from the stove to the pan.
- 2). Heat a gas or a liquid like water or air. As parts of it heat, they will rise while the cooler parts fall to the bottom of the container. Then, as the warm parts cool, they will fall, making room for cooler parts to heat up and take their place. This is convection -- the circulation and transfer of heat through a liquid or gas. If you put water in the pan you used in step 1, you can experience both conduction and convection -- the pan will heat through conduction, and the water within it will heat through convection.
- 3). Place a dark piece of material on the ground on a hot day. It will heat up as the day passes from heated electromagnetic waves travelling through space. This is radiation heat, and it is being transferred directly from the sun. Since you do not have access to space, you cannot create radiation heat transfer yourself, but you can experience and harness it.
