At On 0в°C Pressure Measured By Barometer Is 760 Mm

At on 0°C pressure measured by barometer is 760 mm. what will be pressure at 100°C (A) 780 mm (B) 760 mm (C) 730 mm (D)…

Answers:

The correct option (D) None of these.

Explanation:

 At T₁ = 273K, P₁ = 760mm

T₂ = 373K

 & volume is constant hence P ∝ T

  (P₂/P₁)   = (T₂/T₁)

∴ P₂ = 760 × {373/273}

  P₂ = 1038mm
