When a system is taken from state i to state f along the path iaf, it is found that Q = 50 cal and W = 20 cal. Along the path ibf Q = 36 cal. W along the path ibf is (a) 14 cal (b) 6 cal (c) 16 cal (d) 66 cal

Answer: (b). Path iaf: Δ U = Q - W = 50 - 20 = 30 cal. Path ibf: W = Q - Δ U = 36 - 30 = 6 cal So the answer is (b) 6 cal.

When a system is taken from state $i$ to state $f$ along the path iaf, it is found that $Q = 50$ cal and $W = 20\text{ cal}$ . Along the path $ibf\ Q = 36\text{ cal}.\ W$ along the path $ibf$ is

Show answer and solution

Answer: (b)

Path iaf: $\Delta U = Q - W = 50 - 20 = 30\ \text{cal}$ .
Path ibf: $W = Q - \Delta U = 36 - 30 = 6\ \text{cal}$
So the answer is (b) $6\text{ cal}$ .
