The rear defroster of your car is a pattern of thin metal strips across the window. When you turn the defroster on, current flows through those metal strips. Why are wires attached to both ends of the metal strips?

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
