Heat and Mass Transfer The heat transfer from a hot body to a cold body is directly proportional to the surface area and difference of temperatures between the two bodies. This statement is called Newton's law of heating Newton's law of cooling Stefan's law First law of thermodynamics Newton's law of heating Newton's law of cooling Stefan's law First law of thermodynamics ANSWER DOWNLOAD EXAMIANS APP
