The expansion of 2.0 moles of a monatomic ideal gas from stateA to state B is P

Question

The expansion of 2.0 moles of a monatomic ideal gas from stateA to state B is PA = PB = 600N/m2 and VA = 3.0m3 ,VB = 9.0m3. (a)       i. Calculate the work doneby the gas as it expands       ii. Calcuate the change ininternal energy as it expands       iii. Claculate the heatadded to or removed from the gas during the expansion The expansion of 2.0 moles of a monatomic ideal gas from stateA to state B is PA = PB = 600N/m2 and VA = 3.0m3 ,VB = 9.0m3. (a)       i. Calculate the work doneby the gas as it expands       ii. Calcuate the change ininternal energy as it expands       iii. Claculate the heatadded to or removed from the gas during the expansion

Explanation / Answer

i.   work = pressure * change in volume = 600 * (9-3) =   3600 Joules . ii.    change in internal energy = (3/2) n R T = (3/2) p V = (3/2) * 600 * 6 =   5400 Joules . iii    heat added = work done +change in internal energy =   3600 + 5400 =   9000Joules
