The density of phosgene $(COCl_2)$ gas at $STP$ is........

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

During the evaporation of a liquid,the temperature of the liquid ..

$A$ mixture of $CO$ and $N_2$ gases of equal mass is filled in a cylinder. What will be the ratio of their partial pressures?

Cooking is fast in a pressure cooker,because

$x \ g$ of molecular oxygen $(O_2)$ is mixed with $200 \ g$ of neon $(Ne)$. The total pressure of the nonreactive mixture of $O_2$ and $Ne$ in the cylinder is $25 \ bar$. The partial pressure of $Ne$ is $20 \ bar$ at the same temperature and volume. The value of $x$ is $....$ [Given: Molar mass of $O_2 = 32 \ g \ mol^{-1}$. Molar mass of $Ne = 20 \ g \ mol^{-1}$]
