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 = 2.4 atm to P2 = 1.1 atm. Then the gas expands at constant pressure, from a volume of V₁ = 5.8 L to V2 = 9.9 L, where the temperature reaches its original value. See the figure ( Figure 1). Figure A Part A P P₁ P2 1 Ο a 0 Vi V2 V Calculate the total work done by the gas in the process. Express your answer to two significant figures and include the appropriate units. με ? W= = Value Units Submit Request Answer Part B Calculate the change in internal energy of the gas in the process. Express your answer with the appropriate units. HÅ AU = Value Submit Request Answer Part C Units Calculate the total heat flow into or out of the gas. Express your answer to two significant figures and include the appropriate units. <1 of 1
