A relation between vapour pressure and the temperature is known as

A container contains $$O_{2}$$ and $$N_{2}$$ in equal molar concentration at same temperature, what is the $$CORRECT$$ statement about the average molar kinetic energy of the two gasses?

Lowering in vapour pressure is highest for:

A mixture contains 16 g of oxygen ,28g of nitrogen and 8g of methane.Total pressure of the mixture is 740mm. What is the partial pressure of nitrogen in mm?

if the mass ratio of hydrogen gas is to oxygen gas in a mixture is 1:2 then the ratio of their number of molecules is:

A container of volume $$40$$ liters consist of some gas at a pressure of 2 atm and temperature of $$300 K$$. It is heated to $$400 K$$ such that half of the gas escape and volume changes to 60 liters. The new pressure of the gas at the final condition will be:

In an ideal solution of non-volatile solute B in solvent A in 2: 5 molar ratio has vapour pressure 250 mm. If another solution in ratio 3: 4 prepared then vapour pressure above this solution is:

A sample of 16g charcoal was brought into contact with $$  C{  H}_{  4}$$ gas contained in a vessel of 1 litre at $$ 2{ 7 }^{0  }C  $$ . The pressure of gas was found to fall from 760 to 608 torr. The density of charcoal sample is 1.6g/ $$ c{  m}^{ 3 }  $$. What is the volume of the $$  C{  H}_{  4}$$ gas adsorbed per gram of the adsorbent at 608 torr and $$ 2{ 7 }^{0  }C  $$ ?

 Equal weight of $${CH}_{4}$$ and $${H}_{2}$$ are mixed in a container at $$25^o C$$, the fraction of total pressure exerted by hydrogen is :

The total kinetic energy (in joules) of the molecules in $$8 \ g$$ of methane at $$27^oC$$ is:
