Convection: The transfer of heat by the movement of a fluid (liquid or gas) between areas of different temperature. These are some of the observations in our day-to-day life. Warm air is less dense than cold air, and so convection currents can form in the presence of a temperature gradient. The moving particles of a warm soild material can increase the heat energy of the particles in a cooler solid material by transferring it directly from one particle to the next, when it is placed very near by it. Temperature is a measure of how hot or cold a substance feels and it is measured in degrees Celsius (C). In studies of chemical and mechanical engineering, the heat transfer coefficient is used for calculating the heat transfer that happens between a fluid and a solid, between fluids that are separated by a solid, or between two solids. The heat transfer rate of a body due to convection is directly proportional to the temperature difference between the body and its surroundings. An example of data being processed may be a unique identifier stored in a cookie. This is called conduction of heat. As you heat a solid, these vibrations get larger and larger so that neighbouring particles 'bump' into each other, transferring the vibrations. Similarly, when you start your bike engine, it is at ambient temperature, but after some time has passed, the engine, along with the nearby components, becomes hot.
