When work is done by a system then it is taken as positive, and when work is done on the system by the surrounding then it is taken as negative. Problem sets 1-9. Explanation: According to the first law of thermodynamics, the energies are converted from one form to another form. After some time they attain a common temperature and then they are in a thermal equilibrium. As the energy can neither be transmitted nor be absorbed, the total energy of an isolated system is always constant. If Q is the amount of heat transferred to the system and W is the amount of work transferred from the system during the process, then the net energy (Q – W) is stored in the system. The main function of heat engine is to produce work output continuously by consuming heat energy given to the system. Give Its Limitations And Importance.?
