When the absolute temperature of ideal gas is doubled and pressure is halved, the volume of gas

Options

  1. Awill be half of original volume
  2. Bwill be 4 times the original volume
  3. Cwill be 2 times the original volume
  4. Dwill be 1 / 4 th times the original volume

Correct answer

B. will be 4 times the original volume

Step-by-step solution

Given, final temperature (T₂ )=2 (T₁ ) initial temperatue Final pressure (p₂ )=2 (p₁ ) 2 initial pressure According to gas law, p₁ V₁ T₁ = p₂ V₂ T₂ p₁ V₁ T₁ = p₁ V₂ 2 2 T₁ V₂=4 V₁ Volume increase by 4 times.
