There are 6 xx 10^(21) hydrogen molecule...

There are `6 xx 10^(21)` hydrogen molecules in a vessel of volume `200 cm^(3)`. Its tempera-ture is `27^(@)C` and the pressure is `10^(5) Nm^(-2)`. If the temperature be raised to `47^(@)C`, then in what ratio the following qunatities would change (i) number of molecules per unit volume (ii) pressure of the gas is the vessel and (iii) average kinetic energy of hydrogen ?

Text Solution

Verified by Experts

The correct Answer is:
(i) It remains unchanged `(3 xx 10^(19) "per cm"^(3))` , (ii) `15 : 16` , (iii) `15 : 16`
