If $\mathrm{n}$ is the number density and $\mathrm{d}$ is the diameter of the molecule, then the average distance covered by a molecule between two successive collisions (i.e. mean free path) is represented by :
For a given gas at $1\,atm$ pressure, $rms$ speed of the molecules is $200\,m/s$ at $127\,^oC.$ At $2\,atm$ pressure and at $227\,^oC,$ the $rms$ speed of the molecules will be
One litre of oxygen at a pressure of $1\, atm$ and two litres of nitrogen at a pressure of $0.5\, atm$ are introduced into a vessel of volume $1L$. If there is no change in temperature, the final pressure of the mixture of gas (in $atm$) is
The temperature of an ideal gas at atmospheric pressure is $300\,K$ and volume $1\,m^3$. If temperature and volume become double, then pressure will be
An air bubble doubles its radius on raising from the bottom of water reservoir to be the surface of water in it. If the atmospheric pressure is equal to $10\, m$ of water, the height of water in the reservoir is ..... $m$
An ideal gas has an initial pressure of $3$ pressure units and an initial volume of $4$ volume units. The table gives the final pressure and volume of the gas (in those same units) in four, processes. Which processes start and end on the same isotherm
