Question

Given below are two statements
Statement-I: When

\mu

amount of an ideal gas undergoes adiabatic change from state

\left( {{P_1},\,{V_1},\,{T_1}} \right)

to state

\left( {{P_2},\,{V_2},\,{T_2}} \right),

then work done is

W = \frac{{\mu R\left( {{T_2} - {T_1}} \right)}}{{1 - \gamma }},

where

\gamma = = \frac{{{C_p}}}{{{C_v}}}

and R = universal gas constant.
Statement-II: In the above case, when work is done on the gas, the temperature of the gas would rise.
