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 m³ mol. The thermometer is calibrated at the triple point of water. What is the temperature reading at 100°C, and what is the percentage error of the meter at 100°C? 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, B→C, C→A.
