In a system with no friction what is the mathematical relationship between kinetic and potential energy? 1. As potential Energy increases, kinetic energy increases
2. Potential and kinetic energy are always the same
3. As kinetic energy increases, potential energy decreases

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
