The law of reflection states that the angle of incidence and the angle of reflection are always a: greater than 45 degrees each b: less than 45 degrees each c: equal in measure d: different in measure

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
