At What Temperature Volume Of Ideal Gas Becomes Triple 819в°C

At what temperature volume of an ideal gas becomes triple (A) 819°C (B) 182°C (C) 646°C (D) 546°C

Answers:

The correct option (D) 546°C

 Explanation:

 At constant press use

 V ∝ T

(V₂/V₁) = (T₂/T₁)

given: V₂ = 3V₁

∴ 3 = (T₂/T₁)

 ∴ T₂ = 3 T₁

= 3 × 273 K

 T₂ = 819 K

 i.e. T₂ = (819 – 273)°C

 i.e. T₂ = 546°C
