Homework Help: Thermodynamics - help

  1. Apr 12, 2010 #1
    Two moles of an ideal monoatomic gas doubles its initial volume in an isothermal expansion from state A to state B. The gas is then compressed isobarically to state C and finally heated isochorically until it returns to state A. The molar gas constant is R = 8.314 J mol–1 K–1 and Boltzmann's constant is 1.38 × 10–23 J K–1.

    (a) If state C corresponds to a pressure P = 7 atm (1 atm = 1.013 × 105 Pa) and temperature T = 634 °C, determine the temperature of the gas in state B in K.

    You will need to show some work so we can guide you in the right direction. For a start, you could write out the equations that relate A to B, B to C, and C to A.
