The themodynamic system is taken from state A to state B to state C , and then back from state A to p-V diagram of fig - 21.24 a . The vertical scale is set by `p_s = 20 `Pa and the table in fig . 21-24 by inserting a plus sign a minus sign or a zero in each indicated cell . (h ) what is the set work done by the system as it moves once through the cycle ABCA ?

Explanation

`(a) Q gt 0 , (b ) W gt 0 , (c ) W=0 , (d) Delta E_( I n t) gt 0 , (e ) Q lt 0 , (f ) W lt 0 , (g ) Delta E_( I nt ) lt 0 , (h) - 5.0 J`
