A gas is taken through a cyclic process. The change in internal energy along the path from \( \mathrm{c} \) to a is -160
P
\( \mathrm{J} \). Heat transferred along the path from a to \( \mathrm{b} \) is 200 \( \mathrm{J} \) and \( 40 \mathrm{~J} \) from path \( \mathrm{b} \) to \( \mathrm{c} \). Then -
(1) work done in the cycle is less than \( 80 \mathrm{~J} \).
(2) work done in path abc is \( 80 \mathrm{~J} \).
(3) work done in path ab is \( 160 \mathrm{~J} \).
(4) net heat transferred is less than \( 80 \mathrm{~J} \).
