A certain gas diffuses four times as quickly as oxygen. The molecular weight of the gas is 

The density in grams per liter of ethylene $$ (C_2H_4) $$ at STP is-

Two contains are filled, each with a different gas,The two containers are at the same temperature.Suppose that the molecular weight of the two gases are $$ M_A and M_B $$ the average moments (in magnitude) of the molecules are related as:

At what temperature the mean speed of the molecules of hydrogen gas equals the escape speed from the earth?

The average speed v and r.m.s. speed $$\bar { v } $$ of the molecules are related as

The minimum amount of energy that the reacting molecules must possess at the  time of collisions in order to produce effective collision is called

At NTP the density of a gas is $$1.3 kg\ m^{-3} $$ and the velocity of sound propagation in the gas is$$ 330\ ms^{-1} $$. The degree of freedom of the gas molecule is 

A monatomic ideal gas undergoes a process in which the ratio of P to V at any instant is constant and equals to 1. What is the molar heat capacity of the gas? 

The temperature at which the average speed of oxygen molecules is double that of the same molecules at $$0^oC$$ is _________.

$$4.48L$$ of an ideal gas at STP requires 12.0 calories to raise its temperature  by $${ 15 }^{ 0 }$$C at constant volume. The $${ C }_{ p }$$ of the gas is:
