For process 0 to 6, which of the following is a constant? p is pressure, V is volume, and T is the temperature. Select all apply. pV diagram T/p pV T p T/V V you cant see the graph, but from 0 to 6, pressure is constant and volume is decreasing. the point at which 0 is at is on the curve for isothermal, but 6 is off of that curve
