question_answer 20)

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

Answer:

                  (d)
