Unformatted text preview: Practice Exam 1 R = 8.314 J/(K mol), 1bar = 10 5 Pa, 1 L =10-3 m 3 1 . True/False. Classify the statements below as either True or False (No explanation required). (a) If you know the pressure, temperature and the number of moles of a gas, you have all the information to exactly reproduce the same state of the gas in a laboratory. (b) The energy of any gas always remains constant in an isothermal process. (c) The work done by the system is always maximum in a reversible process. (d) Entropy of a system increases more in an irreversible process than in a reversible one with the same initial and final states. (e) In a reversible adiabatic process, the entropy of a system remains constant. 2. You have one mole of ideal gas in a cylinder with a piston of mass m and unit area . Initially, the pressure by the weight of the piston is balanced with the internal pressure of the gas (ignore the effect of atmospheric pressure). The temperature of the gas inside the cylinder is kept constant at T effect of atmospheric pressure)....
