Considering the air as an ideal gas, find its final temperature at the end of compresssion. O 511.51 K O 521.51 K O 767.51 K O 735.90 KA piston cylinder device contains a liquid-vapor mixture of water at 500K. During a constant pressure process, 700 KJ of heat is transferred to the water. As a result, part of the liquid in the cylinder vaporizes. Determine the entropy change of the water during this process O 2.4 KJ/K O 1.4 KJ/K O 0.7 K/kg O 5.4 K/kgIn the process where the product of pressure and the volume is constant, a gas compression is carried out from an intial pressure of 200 kPa to a final pressure of 800 kPa. Consisting that the initial specific volume is 0.10 m3/kg, determine the work done per kilogram of gas. O -32.5 kJ/kg O -27.7 kJ/kg O -41.51 kJ/kg O -52.5 kJ/kg
