Given:

Initial volume, V₁ = V

Final volume, V₂ = 2 V

Relation --> VP² = Constant

Initial temp, T₁ = T

To Find:

The final temperature of the gas, i.e., T₂.

Calculation:

- For 1 mole of gas,

PV = RT

⇒ P = RT/V

- Putting it in the given relation, we get:

V (RT/V)² = Constant

⇒ T²/V = Constant

- Now using this relation, we get:

T₁²/V₁ = T₂²/V₂

⇒ T²/V = T₂²/2 V

⇒ T₂² = 2 T²

T₂ = T√2

- So the final temperature will be  T√2.

- Hence the correct answer is option (B) T√2.
