$A$ person living in $Shimla$ observed that cooking food without using a pressure cooker takes more time. The reason is that at high altitude:

$A$ container contains equal masses of $H_2$,$He$,$CO_2$,and $Ne$ at a certain temperature. Which of the following gases exerts minimum partial pressure?

Explain the states of matter.

$A$ $10 \ L$ 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:

Hydrogen gas diffuses six times faster than gas $A$. The molar mass of gas $A$ is

The total pressure of a mixture of two gases is equal to .......
