1. A ideal gas of density ρ = 0.2 kg m-3 enters a chimney of height h at the rate of α = 0.8 kg s-1 from its lower end, and escapes through the upper end as shown in the figure. The cross-sectional area at the lower end is A1 = 0.1 m2 and at the upper end is A2 = 0.04 m2. The pressure and the temperature of the gas at the lower end are 600 kPa and 300 K, respectively, while its temperature at the upper end is 150 K. The chimney is heat insulated so that the gas undergoes adiabatic expansion. Take R = 10 J mol-1 K-1 and the ratio of specific heats of the gas γ = 2. The pressure (in kPa) and temperature (in K) are related by P ∝ Tγ.
The chimney is 10 m2 and the ratio of specific heats of the gas (γ) is/are correct?

2. A thermally isolated cylindrical closed vessel of height 8 m is kept vertically. It is divided into two equal parts by a diathermic (perfect thermal conductor) frictionless partition of mass 8.3 kg. Thus the partition is held initially at a distance of 4 m from the top, as shown in the schematic figure below. Each of the two parts of the vessel contains 0.1 mole of an ideal gas at temperature 300 K. The partition is now released and moves without any gas leaking from one part of the vessel to the other. When equilibrium is reached, the distance of the partition from the top (in m) will be ____.
(take the acceleration due to gravity = 10 m s-2 and the universal gas constant = 8.3 J mol-1 K-1)
