A certain sample of gas has a volume of 0.2 ~L at one atmosphere pressure and 273.15 K. What is the volume of gas at 273.15^ C at same pressure?

Options

  1. A2.703 ~L
  2. B0.2 ~L
  3. C0.4 ~L
  4. D5.406 ~L

Correct answer

C. 0.4 ~L

Step-by-step solution

V ₁=0.2 ~L , ~T ₁=237.15 ~K ~V ₂=? , ~T ₂=273.15+273.15=546.30 ~K According to Charle's law, V ₁ ~T ₁ = V ₂ ~T ₂ (at constant P and n ) V ₂= V ₁ T ₂ ~T ₁ = 0.2 546.30 273.15 =0.4 ~L
