Question

A diatomic gas is compressed from a volume of 2 m3 to a volume of 1 m3

Answer 1

Answer:

First law of Thermodynamics -

Heat imported to a body in is in general used to increase internal energy and work done against external pressure.

- wherein

dQ= dU+dW

$\Delta U = \Delta Q - W \\ \Delta Q = 150 J \\ W = P \Delta V = 100 N/m^2 (1 m^3 - 2 m^3 ) = - 100 J \\ \Delta V = 150 J - (-100J ) = 250 J$

U is increased by 250 J
