1 mole of H2 gas is contained in a box of volume V = 1.00 m3 at T = 300K. The gas is heated to a temperature of T = 3000K and the 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 the pressure initially.

Best answer

(d)  20 times the pressure initially.
