Calculate the heat abosrbed by a system in going through the cyclic process show in Fig.

Explanation

The cycle is clockwise, thus net wor is done by the gas. As in a cyclic process no change in internal energy takes place, heat supplied is equal to the work done by the gas in one complete cycle. So in this case heat supplied to the gas in given as
`Q =` wor done by the gas, `W`
= area of ellipse
`= pi ab`
Where `a` and `b` aer semi-major and semi-minor axes of the ellipse, respectively, which are given form the figure as
`a = 1.0 xx 10^(5) N//m` and `b = 100 xx 10^(6) m^(3)`
Thus area of ellipse
`Q = W = pi xx 1.0 xx 10^(5) xx 100 xx 10^(-6)`
`= 3.14 xx 10 = 3.14 J`
