7. At a certain process, the specific heat at polytropic process of air is 0.3075kJ/kg- k. Under the same process, air initially at STP is being compressed until the pressure becomes 200kPaa. Determine the final temperature (0C) of air and the heat transferred during compression (kJ/kg). Draw a diagram and show the step by step solution
