Explanation The reversible process is a process that can be converted from the final state to the initial state and the pressure, temperature and the volume of the system remains same as that at the start of the process. The pushing of a block up a frictionless inclined plane can be pushed downward without any loss in the heat as the plane is frictionless and the net work done is also zero. The stretching of a spring by a small amount the internal energy of the spring is conserved and can be converted into the original form just by releasing the small amount of force applied. The net heat and work done is also zero. Conclusion: Since, the net internal energy of the system is conserved and the net heat and the work done is also zero. Thus, option (b) and option (e) are correct. As the heat flows out of the system while lightening a match that can’t be obtained back by any other process so it is not a reversible process...

First law of Thermodynamics

The word thermodynamics consists of two words: thermo- and dynamics. Dynamics means the study of motion. The field of thermodynamics is all about the study of the movement of heat. In a more meaningful way, it is stated as the study of the transfer of en…
