Question:

A system contains oxygen (ideal gas) at 400 K and 100 kPa. As a result of some disturbance, the conditions of the gas change to 404 K and 98 kPa.
(a) Estimate the change in the specific volume (Δv) of the gas using the ideal-gas relation and using Taylor's theorem.
(b) Determine the exact answer using the IG equation of state.
