Question 473: Thermodynamics & KTG

Question

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

Accepted Answer

For path iaf, $$\Delta U = Q - W = 50 - 20 = 30\,cal.$$
For path ibf, $$W = Q - \Delta U = 36 - 30 = 6\,cal.$$

Answer

$$14$$ $$cal$$

Answer

$$6$$ $$cal$$

Answer

$$16$$ $$cal$$

Answer

$$66$$ $$cal$$
