Examples of Heat Transfer in Dorm Rooms


heat transfer

In an average dorm room, there is one window that transfers heat between the inside and outside of the room. This window’s glass is two feet wide and three feet high, and is only 1/8 inch thick. The temperature on the outside of the glass is 21.0 degrees Fahrenheit, while the inside temperature is 33.0 degrees Fahrenheit. The heat transfer rate through this window is approximately 0.1 degrees per hour. The rate of heat transfer in a dorm room window is about 0.1 degF per hour.

Make Sure To Check The Tag On The Fabric

Heat transfer happens when two objects with different temperatures come into thermal equilibrium. The temperature difference between them is small, and the process continues until all of the objects reach a certain temperature. Typical examples of heat transfer include cooling a hot coffee mug or warming a cold can of pop. If you place a metal can containing hot water inside a Styrofoam cup containing cold water, the heat from the hot can moves to the cold water inside the Styrofoam cup, warming it.

Another example of heat transfer through water is through convection. The temperature of a metal pot on a stovetop is a source of heat for the water inside it. As the pot gets hotter, the water in the metal pan becomes hot, conducting heat from the hot metal pot to the water inside. Fluids tend to expand as they heat up, causing the density of the water in the pan to drop. This decrease in density causes circulation currents in the water.
