The ratio of specific heat at constant pressure $(C_p)$ to specific heat at constant volume $(C_v)$ for a diatomic gas is ...........

Write the important physical properties of liquids.

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

$A$ pressure cooker reduces the cooking time because:

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

$50 \ mL$ of hydrogen gas diffuses through a small hole in a container in $20 \ min$. How much time (in $min$) will $40 \ mL$ of oxygen take to diffuse under the same conditions?
