Heat and Mass Transfer Conduction is a process of heat transfer None of these From one particle of the body to another without the actual motion of the particles From a hot body to a cold body, in a straight line, without affecting the intervening medium From one particle of the body to another by the actual motion of the heated particles None of these From one particle of the body to another without the actual motion of the particles From a hot body to a cold body, in a straight line, without affecting the intervening medium From one particle of the body to another by the actual motion of the heated particles ANSWER DOWNLOAD EXAMIANS APP
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 First law of thermodynamics Stefan's law Newton's law of cooling Newton's law of heating First law of thermodynamics Stefan's law Newton's law of cooling ANSWER DOWNLOAD EXAMIANS APP
