Example problem 2.1 1.00 mol of an ideal gas (the system) is confined in a piston and cylinder assembly similar to that shown in figure on right. The initial temperature is 300. K, and the initial pressure is 0.200 bar. The surroundings are a water bath at 300. K. a. Write an expression in terms of the system variables for the work in a reversible process in which the volume of the gas is doubled. b. Can you obtain a numerical value for w? Assume that the reversible process is isothermal. Calculate w by evaluating the integral in part (a). Mech stops

5.0 g of nitrogen gas at 20°C and an initial pressure of 2.8 atm undergo a constant-pressure expansion until the volume has tripled. Part C How much heat is transferred to the gas to cause this expansion? Express your answer with the appropriate units. ► View Available Hint(s) Qexp 3000 J Submit Previous Answers ✓ Correct The gas pressure is then decreased at constant volume until the original temperature is reached. Part D What is the gas pressure after the decrease? Express your answer with the appropriate units. View Available Hint(s)
