Engineering Thermodynamics An isolated system is one in which Mass does not cross boundaries of the system, though energy may do so Mass crosses the boundary but not the energy Neither mass nor energy crosses the boundaries of the system Both energy and mass cross the boundaries of the system Mass does not cross boundaries of the system, though energy may do so Mass crosses the boundary but not the energy Neither mass nor energy crosses the boundaries of the system Both energy and mass cross the boundaries of the system ANSWER DOWNLOAD EXAMIANS APP
Engineering Thermodynamics Which of the following is the correct statement of the second law of thermodynamics? There is a definite amount of mechanical energy, which can be obtained from a given quantity of heat energy It is impossible to construct an engine working on a cyclic process, whose sole purpose is to convert heat energy into work All of these 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 It is impossible to construct an engine working on a cyclic process, whose sole purpose is to convert heat energy into work All of these It is impossible to transfer heat from a body at a lower temperature to a higher temperature, without the aid of an external source ANSWER DOWNLOAD EXAMIANS APP
