Engineering Thermodynamics Which of the following is the correct statement of the second law of thermodynamics? It is impossible to construct an engine working on a cyclic process, whose sole purpose is to convert heat energy into work It is impossible to transfer heat from a body at a lower temperature to a higher temperature, without the aid of an external source There is a definite amount of mechanical energy, which can be obtained from a given quantity of heat energy All of these It is impossible to construct an engine working on a cyclic process, whose sole purpose is to convert heat energy into work It is impossible to transfer heat from a body at a lower temperature to a higher temperature, without the aid of an external source There is a definite amount of mechanical energy, which can be obtained from a given quantity of heat energy All of these ANSWER DOWNLOAD EXAMIANS APP
Engineering Thermodynamics The general gas energy equation is (where Q1 - 2 = Heat supplied, dU = Change in internal energy, and W1 - 2 = Work done in heat units) Q1 - 2 = dU + W1 - 2 Q1 - 2 = dU/W1 - 2 Q1 - 2 = dU - W1 - 2 Q1 - 2 = dU × W1 - 2 Q1 - 2 = dU + W1 - 2 Q1 - 2 = dU/W1 - 2 Q1 - 2 = dU - W1 - 2 Q1 - 2 = dU × W1 - 2 ANSWER DOWNLOAD EXAMIANS APP
