The ratio of rates of diffusion of gases $X$ and $Y$ is $1:5$ and that of $Y$ and $Z$ is $1:6$. The ratio of rates of diffusion of $Z$ and $X$ is

What will be the pressure at $0\,^oC$ in Kolkata,Chennai,and Mumbai (in $,bar$)?

$A$ hydrocarbon diffuses $3\sqrt{3}$ times slower than hydrogen gas. Identify the hydrocarbon.

The ratio of $\frac{C_p}{C_v}$ for inert gases is

Show the relationship between different units of pressure.

When $0.0168 \ mol$ of $O_2$ obtained from the decomposition of $KClO_3$ is collected over water at $25 \ ^oC$,the volume is $428 \ mL$ and the total pressure is $754 \ mm$. What is the aqueous tension (water vapor pressure) at $25 \ ^oC$ in $mm$?
