M₁ = M,
T₁ = 60 + 273 = 333 K

(as 1/4 th part of air escapes)
If pressure and volume of gas remain constant then
MT = constant

⇒ T₂ = 444K = 171°C
The correct answer is: 171

Similar Physics Doubts

A vessel of volume V = 30 litre contains an ideal gas at temperature. T = 0°C. Keeping temperature constant, a part of the gas is allowed to escape from the vessel causing the pressure to fall down by ΔP = 0.78 atm. Find the mass of the gas released. Its density under normal conditions is p= 1.3 g/it Correct answer is '30.4'. Can you explain this answer?
