A gas occupying a volume of 10^(-2) m ^(3).at a pressure of 5 atmosphe

1.	A gas occupying a volume of 10^(-2) m ^(3).at a pressure of 5 atmospheres expands isothermally to a pressure of 1 atmosphere. Calculate the work done.
Answer» Solution :`W =2 . 303 RT log _(10) (V _(2) //V _(1)) = 2. 303 P _(1) V _(1) log _(10) (P_(1) //P_(2)) = 2. 303 xx 5 xx 101325 xx 10 ^(-2) log _(10) (5//1) = 8. 155 xx 10 ^(3) Nm`
