\(1\) mole of \(\mathrm{H}_{2}\) gas is contained in a box of volume \(V = 1.00 ~\text m^{3}\) at \(T = 300 ~\text{K}\). The gas is heated to a temperature of \(T = 3000~\text{K}\) and the gas gets converted to a gas of hydrogen atoms. The final pressure would be:
(considering all gases to be ideal)
1. same as the pressure initially.
2. \(2\) times the pressure initially.
3. \(10\) times the pressure initially.
4. \(20\) times the pressure initially.
