When the heated object is put in contact with the cooler object, the molecules in the cooler object begin to vibrate faster, which means it is gaining heat energy and becoming warmer. Given two objects, the particles within the hotter object move more rapidly than those in the cooler object. ConductionĬonduction is the transfer of heat through items that are in direct contact with one another. There are three ways that heat transfers from one location to another: conduction, convection and radiation. When heat is pulled from a room (cooling), at some point heat energy will return into the cooler space and will need to be removed again. When hot air enters a room, the items inside the room (furniture, walls, carpet, etc.) will increase in temperature as the hot air decreases in temperature until the point where the temperature of all items inside the room is equal. Heat energy will always follow the rules of thermodynamics: it will move to a cooler place than the location that it is currently located. Whether we are attempting to heat a building or cool a building, heat energy must be moved from one location to another.
