The problem statement, all variables and given/known data A mass of gas occupying volume V1 = 2 m3 at the pressure P1 = 4*10^5 Pa performs the cycle represented in the Figure that i have uploaded.What is the work of gas in this cycle, knowing that the pressure P2 = 10^5 Pa 2. Relevant equations Work=1/2 * (P1 - P2) * (V1 - V3) 3. The attempt at a solution The work is the area within the triangle. 1/2 base * height = 1/2 * (P1 - P2) * (V1 - V3) The question that i have is how do i find V3?
