Question

In the figure shown here, the work done in the process ACBA is ______.

पर्याय

• 4P₀V₀

• 6P₀V₀

• -2P₀V₀

• -4P₀V₀

Answer 1

In the figure shown here, the work done in the process ACBA is -2P₀V₀.

Explanation:

In the P-V graph, the work is represented by the area enclosed by the curve.

So area enclosed by the curve(A) 

= `-1/2xx(3"P"_0-"P"_0)xx(3"V"_0-"V"_0)`

= - 2P₀V₀

The gas's volume is decreasing as indicated by the negative sign in this instance.
