Convection

Convection
Moving air is generally thought of as convection. When you open a hot oven, hot air rises into your face. Rising hot air is called convection. When you open a refrigerator in you bare feet, you can feel the cold air falling against your skin. This falling cold air is called convection. Even with no wind outside in the winter, when you open the door to your house, warm air will move out the door and rise through the cold air outside. As this warm air leaves your house, cold air from outside moves in to take its place. Understanding convection can help you slow down heat loss from your house in the winter or air-conditioned air loss in the summer. Knowing how convection works will help you keep your home more comfortable and save you money.
