1.8-1. For the system considered in Example 1, calculate the energy of the state with P = 5 x 104 Pa and V = 8 10-3 m. Example 1 A particular gas is enclosed in a cylinder with a moveable piston. It is observed that if the walls are adiabatic, a quasi-static increase in volume results in a decrease in pressure according to the equation py5 = constant (for Q = 0) P (Pascal)- 105 105/32 py5 = constant 10-3 V (m)- B D 8 10-3
