    Five moles of carbon dioxide (CO2), initially 3 atm and 300 K, is trapped inside a piston-cylinder assembly. It is then allowed to expand against atmospheric pressure adiabatically. The constant- pressure heat capacity of CO2 is given by the following equation: p = 5.4574 (1.045 × 10-3)(T/K)-(1.157 × 105)(T/K)-2 (a) If we assume that the expansion is infinitely slow and quasi-static, calculate the final temperature and total volume of the carbon dioxide gas when it reaches 1 atm. Also calculate...

    4 (30 points). A rigid tank that is initially evacuated is connected through a valve toa supply line that carries helium at 1 MPa and 300 K. Now the valve is opened, and helium is allowed to flow slowly intothe tank until the pressure reaches IMPa P2). The final temperature and mass of the helium gas in the tank are: T2 300 K and m2 1 kg. Determine the direction (Is heat transferred to or from the tank?) and amount...

    A tank with a constant volume of 5.89 m3 contains 15 moles of a monatomic ideal gas. The gas is initially at a temperature of 300 K. An electric heater is used to transfer 56500 J of energy into the gas. It may help you to recall that CVCV = 12.47 J/K/mole for a monatomic ideal gas, and that the number of gas molecules is equal to Avagadros number (6.022 × 1023) times the number of moles of the gas....
