**1 mole of H2 gas is contained in a box of volume V = 1.00 m3 at T = 300 K. The … 10 times the pressure initially (d) 20 times the…**

###### Answers:

(d) The situation is shown in the diagram, H_{2} gas is contained in a box is heated and gets converted to a gas of hydrogen atoms. Then the number of moles would become twice.

According to gas equation,

PV= nRT

P = Pressure of gas, n = Number of moles

R = Gas constant, T = Temperature PV=nRT

As volume (V) of the container is constant. Hence, when temperature (T) becomes 10 times, (from 300 K to 3000 K) pressure (P) also becomes 10 times, asP∝ T.

Pressure is due to the bombardment of particles and as gases break, the number of moles becomes twice of initial, so n_{2} = 2n_{1 }
