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

If the force applied to an object remains constant, is more power needed for the object to move faster ? explain

Which accounts for an increase in the temperature of a gas that is kept a constant volume
