List the different units of gas pressure.

$A$ 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?

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

In which of the following gas mixtures does Dalton's Law of Partial Pressure not apply? Why?
$(i)$ $CO_2 + O_2 + N_2$
$(ii)$ $CO + O_2$
$(iii)$ $NH_3 + HCl$
$(iv)$ $HCl + O_2$

In a closed vessel at $25 \, ^oC$ temperature,$4 \, mole$ $O_2$,$3 \, mole$ $Cl_2$,and $3 \, mole$ $N_2$ are mixed,and the total pressure is found to be $50 \, bar$. Find the partial pressure of each gas.

Where will the boiling point be lower: at the seashore or on a mountain? Why?
