Convection describes the transfer of thermal energy in liquids and gases. The most used method of
transferring thermal energy is to heat a substance and then in turn allow the substance to move Cheap Ozzie Smith Jersey , therefore carrying the thermal energy to a new location. This is called convection. Convection is used in our everyday lives without us even realizing; steam from a tea kettle, hot exhaust fumes from cars, and even smoke from fires all carry thermal energy from one place and disperse it to another. As stated before, this process relies on two characteristics of liquids and gases. One is that they must flow, carrying thermal energy with them Cheap St. Louis Cardinals Hats , and the other is that warmed liquids and gasses must rise in their cooler surroundings.

Since warm air rises, it is able to transfer thermal energy from one energy source to another. Convection is known as the process of transferring thermal energy by the movement of warm liquids and gasses to cooler surroundings. A perfect example to better understand convection is to think of a radiator in a closed room. With the radiator acting as the energy source, the air near the radiator is warmed and soon rises, as it moves upward, the air interacts with outside things such as the walls and the furniture. Its molecules
