The temperature at which the vapor pressure of a liquid becomes equal to the atmospheric pressure is called.....

Deep sea divers use a mixture of which gases for respiration?

The ratio of rates of diffusion of gases $A$ and $B$ is $1 : 0.707$. If the molecular weight of $B$ is $32$,the molecular weight of $A$ is

The total pressure of a mixture of non-reacting gases $X$ $(0.6 \ g)$ and $Y$ $(0.45 \ g)$ in a vessel is $740 \ mm$ of $Hg$. The partial pressure of the gas $X$ is $........ \ mm$ of $Hg$. (Nearest Integer) (Given: molar mass $X = 20 \ g \ mol^{-1}$ and $Y = 45 \ g \ mol^{-1}$)

At $27^{\circ} C$, a closed vessel contains a mixture of equal weights of helium (mol. wt. = $4$), methane (mol. wt. = $16$) and sulphur dioxide (mol. wt. = $64$). The pressure exerted by the mixture is $210 \ mm$. If the partial pressures of helium, methane and sulphur dioxide are $p_1, p_2$ and $p_3$ respectively, which one of the following is correct?

On what factors does the stability of the state of matter depend?
