A constant volume gas thermometer of volume 1x10-3 m3 contains 0.05 mol of gas. It is assumed that the gas obeys the perfect gas law, PV = RT ; but in fact, a its behaviour is better described by the equation P+- (V-b)= RT , 2 V. m m where a=0.8 Nm*mol-2 and b=3x10-5 m mol. The thermometer is calibrated at the triple point of water. What is the temperature reading at 100C, and what is the percentage error of the meter at 100C? One mole ideal gas (N2) go through the following cycle: A B, isothermal reversible process; B C, isochoric process; C A, reversible adiabatic process. Assume TA= 1000 K, VA= 1dm2, VB=20 dm', C, = 2.5 R. (1) Draw the P-V diagram for the cycle. (2) Calculate the T, P, V at A, B, C state. (3) Calculate AU, AH, Q, W for each process: AB, BC, CA.
