Under similar conditions of temperature and pressure gas having highest rate of diffusion is

If helium and oxygen gas are allowed to escape out of a container containing equal amount of He and O_2 under slmllar conditions of temperature and pressure the ratio of rate of diffusion of O_2 to that of He is

Under identical conditions of temperature and pressure the ratio of the rates of effusion of O_(2) and CO_(2) gases is given by

A. Rate of diffusion of H_2 is 1.44 times of He. R: Under similar conditions of temperature and pressure all gases diffuse with same velocity.

Equal volumes of all gases under similar conditions of temperature and pressure contain equal number of atoms.

Two flasks A and B of equal capacity of volume contain SO_3 and CO gas respectively under similar conditions of temperature and pressure. Then, which of the following statement is true?

A bag contains 0.32 g of oxygen. The same valume of an unknown gas A under similar conditions of temperature and pressure weigh 0.26 g . The gas A is known to contain only C and H in 1:1 ratio. The molecular formula of the compound is

Assertion: Atoms can neither be created nor destroyed. Reason: Under similar condition of temperature and pressure, equal volume of gases does not contain equal number of atoms.

Under simuliar conditions of temperature and pressure, in which of the following gases the velocity of sound will be largest?

Under simuliar conditions of temperature and pressure, in which of the following gases the velocity of sound will be largest?

Assertion: Under similar conditions of temperature and pressure, O_(2) diffuses 1.4 times faster than SO_(2) . Reason: Density of SO_(2) is 1.4 times greater than that of O_(2) .
