Question
Consider the following volume-temperature ( V - T ) diagram for the expansion of 5 moles of an ideal monoatomic gas. Considering only P-V work is involved, the total change in enthalpy (in Joule) for the transformation of state in the sequence X Y Z is ________. [Use the given data: Molar heat capacity of the gas for the given temperature range, C _ V , m =12 ~J ~K ^ -1 mol ^ -1 and gas constant, . R =8.3 ~J ~K ^ -1 ~mol ^ -1 ]
