Name three different units of energy used to measure heat and describe what type of situations each is usually used.

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

In a voltaic cell, electrons flow from the (positive/negative) to the (positive/negative) terminal.
