Awell - instulated cylinder piston system shown below initally contains an ideal gas (cp=30 j/mol k) at 10 bar, 50 degrees celcius and a volume of 0.15 m3.the piston has a mass of 10kg and a diameter of 50cm. cylinder mass is 5kg. both the cylinder and piston are made of steel (specific heat=0.5 kj/kg k). outside pressure is 1 atm. the piston is initially held in position by a latch. the latch is removed and after some time the pistin comes to rest at an equilibrium position. assuming that the temperatures of the piston, the cylinder and the gas are always equal, and there is no heat transfer between the sysetm and the surroundings, calculate the final temperature of the gas, the cylinder and the piston.
