Question

A gas is initially at 1 atm pressure. To compress it to \(\frac 14\)th of its initial volume, essential pressure to be applied is

(A) 1 atm

(B) 2 atm

(C) 4 atm

(D) \(\frac 14\) atm

Answer 1

Correct option is (C) 4 atm

According to boyle's law,

P₁V₁ = P₂V₂

⇒ 1.V = V₄.P₂

⇒ P₂ = 4 atm
