A 15.0-L volume of an ideal gas in a cylinder with at piston is at a pressure of 2.8 atm. Enough weight is suddenly removed from the piston to lower the external pressure to 1.4 atm. The gas then expands at constant temperature until its pressure. is 1.4 atm. The change in the internal energy of a system, AE, for an isothermal expansion of an ideal gas is 0. Use this information in your calculations for this problem. Part B Find the change in enthalpy, AH, for this change in state Express your answer using two significant figures.
