Gas Laws & Ideal Gas Equation question from MHT CET 2025 (22 Apr, Shift 2)

Answer: (c)

1. Closed vessel: $P \propto T \Rightarrow \dfrac{\Delta P}{P} = \dfrac{\Delta T}{T}$.
2. $0.023 = \dfrac{4}{T} \Rightarrow T = \dfrac{4}{0.023} \approx 174$ K
3. No option matches exactly; with $2.5\%$ the result is $\dfrac{4}{0.025} = 160$ K.
4. So the intended answer is (c) 160 K.
