One mole of n gas is contained at 273 k and a pressure of latm. the addition of 3000 joules heat to the gas at constant pressure causes 832 joules of work to be done during expansion, calculate: 1750 (i) the final state of the gas (ie, v and t) (ii) the values for du and dh for the change of state, (iii) the values of c, and cp for n2 (iv) draw a schematic diagram to represent the system, the work done on the surroundings by the system and the work done by the system on the surroundings. r = 0.082057 l. atm/ mole. k = 8.314 j/mole. k = 8.314 kj/kmole. k
