Absolute zero is the temperature at which,

In a closed container,the number of oxygen and hydrogen molecules are equal at a pressure of $740 \, mm$. If oxygen is removed from the system,the pressure will be:

The ratio of rates of diffusion of gases $X$ and $Y$ of molecular weights $36$ and $64$ is

The rate of diffusion of $SO_3$,$CO_2$,$PCl_3$ and $SO_2$ gases are in the following order:

$3.2 \, g$ of oxygen gas diffuses in $10 \, minute$. Under similar conditions,$2.8 \, g$ of nitrogen gas will diffuse in ............ $minute$.

$A$ $10 \ L$ vessel contains $1 \ mole$ of an ideal gas with pressure of $P \ atm$ and temperature of $T \ K$. The vessel is divided into two equal parts. The pressure (in $atm$) and temperature (in $K$) in each part is respectively:
