This is usually listed in the nutrition label on the back of any contained foods as a Calorie. /Length 178320 The general defined term of convection is the heat transfer by mass motion of a fluid such as air or water when the heated fluid is caused to move away from the source of heat, carrying energy with it (Georgia State University). When heat is added to a substance, the kinetic energy of individual particles increases, which makes them move faster resulting in a increase in temperature. Temperature is a measure of the average kinetic energy of the particles in a body. When dealing with the transferring of heat and various process related to heat, the terms convection, conduction and radiation are frequently discussed thoroughly. The purpose of this lab was to find the specific heat of something that can, be set on using a calorimeter.
