Question

Constants Calculate the total work done by the gas in the process. Express your answer to two significant figures and include the appropriate units. Consider the following two-step process. Heat allowed to flow out of an ideal gas at constant volume so that its pressure drops from P = 2.9 atm to P2 = 1.3 atm. Then the gas expands at constant pressure, from a volume of V1 = 6.0 L to V2 = 9.3 L , where the temperature reaches its original value. See the figure (Figure 1). MA ?
