A vessel A contains hydrogen and another vessel B whose volume is twice that of A contains same mass of hydrogen at same temperature. Compare
(i) average KE of hydrogen and oxygen molecule.
(ii) root mean square speeds of molecules
(iii) pressure of gases in A and B.
Molecular weight of hydrogen and oxygen are 2 and 32 respectively.

Explanation

To solve the question step by step, we will address each part separately.

### Given:
- Vessel A contains hydrogen.
- Vessel B contains the same mass of oxygen and has a volume that is twice that of vessel A.
- Molecular weights: Hydrogen (H₂) = 2 g/mol, Oxygen (O₂) = 32 g/mol.
- Both vessels are at the same temperature.
