In the reversible adiabatic expansion of a gas the increase in disorder due to an increase in volume is compensated by the decrease in disorder due to a decrease in temperature.
A sample of polystyrene is warmed under reflux in concentrated nitric acid and the clear mixture is poured in water to yield a X coloured precipitate. This precipitate is then extracted with ether and then with NaOH solution followed by washing with water in each extraction. The nitro compounds from the combined final aqueous extract and alkaline extract using concentrated HCl and zinc. The final solution after being diazotized and then cooled is poured into excess of alkaline naphthol to give Y coloured solution. What are the colours X and Y?
