One mole ofan ideal monoatomic gasexpanded irreversibly in two stage expansion . "State"-1""("8.0 bar, 4.0 liters, 300K") "State"-2""("2.0 bar, 16 liters, 300K") "State"-3""("1.0 bar, 32 liters, 300K") Total heatabsored by thegas in theprocess is :

Answer»

<P>116 J
40 J
4000 J
None of these

Solution :`W= - P_(ext)[V_(2)-V_(1)]`
`W_(1)= - 2 [16-4] xx 100 ""= - 2400J`
`W_(2) = - [32 -16] = - 16 xx 100= - 1600 J`
""`-4000`
`q = - W = 4000 J`
