Question

( f=6 quad w=25 J )
( Delta u=frac{f}{2} n R Delta T )
( D omega=n R Delta T )
( Delta omega=D U+Delta W )
( =3 n R D T+n R Delta T )
( =4 n R Delta T )
( =4 times 25=100 J )

# A polyatomic gas with six degrees of freedom does 25J of work when it is expanded at constant pressure. The heat given to the gas is :- (A) 100J (B) 150J (C) 200J (D) 2500
