Q. Two vessels A and B thermally insulated contain an ideal monoatomic gas. A small tube fitted with a valve connects these vessels. Initially the vessels A has 2 litres of gas at 300 K and 2×10⁵ Nm‐² pressure while vessels B has 4 litres of gas at 350 K and 4×10⁵ Nm-² pressure. The valve is opened and the system reaches equilibrium in pressure and temperature. The new pressure will be 3.33×10^n(N/m²). Find n.
