Problem 15.10 Consider the following two-step process. Heat is allowed to flow out of an ideal gas at constant volume so that its pressure drops from P-3.0 atm to P₂ = 1.0 atm Then the gas expands at constant pressure, from a volume of V₁5.9 L to V₂ =9.7 L, where the temperature reaches its original value. See the figure (Figure 1). Figure P₁ P₁ 0 b V₁ 1 of 1 7 of 15 Const Part A Calculate the total work done by the gas in the process.
