Question

The volume of 400 cm³ chlorine gas at 400 mm of Hg is decreased to 200 cm³ at constant temperature. What is the new pressure of gas?

विकल्प

• 1600 mm of Hg

• 200 mm of Hg

• 800 mm of Hg

• 600 mm of Hg

Answer 1

800 mm of Hg

Explanation:

According to Boyle's Law,

P₁V₁ = P₂V₂

`(400 xx 400)/200 = "P"_2`

∴ P₂ = 800 mm of Hg
