At what temperature will the volume of gas becomes 2x, if volume of this gas is x at 0⁰C at constant pressure

Options

(a) 546⁰C
(b) 546 K
(c) 0⁰C
(d) 237⁰C

Correct Answer:

546 K

Explanation:

According to Charle’s law at constant pressure,
V₁ / T₁ = V₂ / T₂
V₁ = x, V₂ = 2x, T₁ = 0 + 273 = 273 K, T₂ = ?
T₂ = (V₂ / V₁) T₁ = (2x / x) × 273 K = 546 K.
