Question

600 c.c. of a gas at a pressure of 750 mm is
compressed to 500 c.c. Taking the temperature
to remain constant, the increase in pressure, is
(a) 150 mm (b) 250 mm
(c) 350 mm (d) 450 mm

Answer 1

Explanation:

the answer is (a) 150mm

Answer 2

(a) 150 mm

Explanation:

We know that P₁V₁ = P₂V₂

Substituting the given values, we get: 750 * 600 = P₂ * 500

So P₂ = 750 * 600 / 500

     = 900mm Hg

Increase in pressure = P₂ - P₁ = 900 - 750 = 150mm

Hence option A is the correct answer.
