An ideal gas, initially at a volume of 2 L and pressure of 7 kPa, undergoes isothermal expansion until its volume is 7 L and its pressure is 2 kPa. Calculate the work done by the gas during this process. Answer in units of kJ. PART TWO:Find the heat added to the gas during this process. Answer in units of kJ

Agas contained within a piston-cylinder assembly undergoes three processes in series: process 12: compression with pv= constant from 1 bar and 1 liter to 4 bar. process 23: constant pressure expansion to 1 liter. process 31: constant volume calculate the pressure and volume at each state, and sketch the processes on a p-vdiagram labeled with pressure and volume values at each numbered stat
