1.	The P-V curves in two cases are shown as a smaller circle x and a bigger circle y, in the figure, Indicate whether the net work done is positive or negative.
Answer» Solution :The cyclic PROCESS x is clockwise. HENCE the work done `W_(1)` is positive. The cyclic process y is anticlockwise. Hence the work done `W_(2)` is negative. `because` Area of `y gt` Area of x `:. W_(2) gt W_(1)` `:.` Net work done will be negative.
