Chapter 14 – Temperature and Heat
... Conduction of heat occurs when the temperature of a body is not uniform. For instance, a rod is heat at one end of the rod. The heat flows from the hot end to the cold end. In the microscopic level, the heat transfer can be described as the transfer of kinetic energy of molecules of high kinetic ene ...
