JEE Advanced 2014 Paper 1 Offline Chemistry - Gaseous State Question 8 English

An ideal gas in thermally insulated vessel at internal pressure = p₁, volume = V₁ and absolute temperature = T₁ expands irreversibly against zero external pressure, as shown in the diagram.

The final internal pressure, volume and absolute temperature of the gas are p₂, V₂ and T₂, respectively. For this expansion

q = 0

T₂ = T₁

p₂V₂ = p₁V₁

p₂V$$_2^\gamma $$ = p₁$$_1^\gamma $$
