Physics - Heat & Thermo Question with Solution | TestHub

Work done by the gas along path $ibf$ is 6 cal

If work done upon the gas is 13 cal for the return path $fi$, then heat rejected by the gas along path $fi$ is 43 cal

If internal energy of the gas at state $i$ is 10 cal, then internal energy at state $f$ is 40 cal

If internal energy at state $b$ is 22 cal and at $i$ is 10 cal, then heat supplied to the gas along path $ib$ is 18 cal
