A gas at a pressure of 2 ~atm is heated from 25^ C to 323^ C and simultaneously compressed of 2 3 rd of its original value. Then the final pressure is

Options

  1. A1.33 ~atm
  2. B6 ~atm
  3. C2 ~atm
  4. D4 ~atm

Correct answer

B. 6 ~atm

Step-by-step solution

Given, p₁=2 ~atm aligned p₂ & =? V₁ & =1 ~L V₂ & = 3 2 T₁ & =298 ~K T₂ & =596 ~K aligned Using combined gas law, we get aligned p₁ V₁ T₁ & = p₂ V₂ T₂ p₂ & = 2 1 298 3 596 2 =6 ~atm aligned
