Problem

A thermodynamic cycle for an ideal gas consists of the following four sequential processes: •

A \to B

: constant pressure expansion at

100\,\text{kPa}

from

V=0.010\,\text{m}^3

V=0.030\,\text{m}^3

, •

B \to C

: constant volume increase in pressure to

300\,\text{kPa}

, •

C \to D

: constant pressure compression at

300\,\text{kPa}

back to

V=0.010\,\text{m}^3

, •

D \to A

: constant volume decrease in pressure back to

100\,\text{kPa}

. Calculate the net work done BY the gas over one complete cycle. Include the algebraic sign in your answer.
