(a) In a thermodynamic process, one mole of an ideal gas is allowed to expand adiabatically and reversibly from a volume of 22.7L/mol at 1 bar and 0C to a volume of 45.4L/mol. (i) Determine the final pressure and temperature. [8 marks] (ii) Calculate the work done during this process. Given: cP=25R;cv=23R. [6 marks] (b) Determine the entropy change (S) of steam during constant temperature process at 573K when the pressure increases from 1106N/m2 to 1.4106N/m2. Given: (TV)P=0.0045+(1.4106P)moLKm3 [14 marks]
