Gas Laws & Ideal Gas Equation

A sample of oxygen gas and a sample of hydrogen gas both have the same mass, same volume and the same pressure. The ratio of their absolute temperature is

Show answer and solution

Answer: (d)

  1. PV=mMRTPV = \dfrac{m}{M}RT; same mm, PP, VV ⇒T∝M\Rightarrow T \propto M.
  2. TO2TH2=322=16\dfrac{T_{O_2}}{T_{H_2}} = \dfrac{32}{2} = 16
  3. So the answer is (d) 16:116 : 1.
