i) Please refer the attached image for calculations.
Pressure is an intensive property as it is independent of the size of the system.
Volume is an extensive property as it depends on the quantity of matter specified in the system.
Work involved in a given change of state are not determined only by the initial and final states, they also depend on the path in which the change is carried out. Hence Work is not thermodynamic property of the system, but are properties of the process and are called path functions.
ii) For expansion process V2 > V1 and ln (V2/ V1) is greater than zero. Since R and T are always positive, the work done by the ideal gas at constant temperature is always positive. Hence there is negative sign before integral.
Work is positive if work is done by the system. It is negative if work is done on the sytem.
