For one complete cycle of a thermodynamic process on a gas as shown in the P-V diagram, Which of following is correct :-

Options

A. `DeltaE_("int")=0,Q lt 0`
B. `DeltaE_("int")=0,Q gt 0`
C. `DeltaE_("int")lt0,Q gt 0`
D. `DeltaE_("int")gt0,Q lt 0`

Answer

A

Explanation

`Delta E_(i n t) = 0` for a complete cycle and for given cycle work is negative ,so from first law of themodynamics `Q` will be negative i.e., `Q lt 0`
