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 P₁ = 3.0 atm to P₂ = 1.7 atm Then the gas expands at constant pressure, from a volume of V₁ = 6.3 L to V₂ = 9.0 L, where the temperature reaches its original value. See the figure (Figure 1). Figure P P₁ P₂ 0 b C V₁ V₂ 1 of 1 V ▼ Part A Calculate the total work done by the gas in the process.
