NEET Chemistry States Of Matter Kinetic Theory & K.E MCQs

One mole of oxygen at 273 K and one mole of sulphur di-oxide at 546 K are taken in two separate containers, then

The root mean square speed of an ideal gas in a closed container of fixed volume is increased from $5 imes {10^4}{\rm{cm}}{{\rm{s}}^{ - 1}}{\rm{to}}10 imes {10^4}{\rm{cm}}{{\rm{s}}^{ - 1}}$. Which statement might correctly explain how the change accomplished?

In two vessels of 1 L each at the same temperature 1 g of ${{\rm{H}}_2}\,\,{\rm{and}}\,\,1\,{\rm{g of}}\,\,{\rm{C}}{{\rm{H}}_4}$ are taken, for these

Kinetic theory of gases assumes that tiny particles called molecules

A bottle of dry ${\rm{N}}{{\rm{H}}_3}$ and bottle of dry ${\rm{HCl}}$ connected through a long tube are opened simultaneously at both ends, the white $\left( {{\rm{N}}{{\rm{H}}_4}{\rm{Cl}}} \right)$ ring first formed will be:

Which is lighter than dry air?

The rate of effusion doesn’t depend on

A bottle of dry ammonia and one of dry hydrogen chloride are connected through a long tube. The stoppers at both ends of the tube are opened simultaneously. The white ammonium chloride ring first formed will be

If temperature of 1 mole of gas is increased by 50\,^\circ C calculate the change in kinetic energy of the system

Which gas has the, same rate of diffusion as that of ${\rm{C}}{{\rm{O}}_2}$ at same $P$ and $T$ ?
