Three processes compose a thermodynamics cycle shown in the PV diagram. Process 1→2 takes place at constant temperature. Process 2→3 takes place at constant volume, and process 3→1 is adiabatic. During the complete cycle, the total amount of work done is 10 J. During process 2→3, the internal energy decrease by 20J and during process 3→1, 20 J of work is done on the system. How much heat is added to the system during process 1→2?

A cylinder made of perfectly non conducting material closed at both ends is divided into two equal parts by a heat proof piston. Both parts of the cylinder contain the same masses of a gas at a temperature t0 = 27° and pressure P0 = 1 atm. Now if the gas in one of the parts is slowly heated to t = 57°C while the temperature of first part is maintained at t0 the distance moved by the piston from the middle of the cylinder will be (length of the cylinder = 84 cm)
