Kinetic Theory Of Gases Mock Tests

The rms speed of oxygen molecules at 27°C is v. If the temperature is doubled and oxygen molecules dissociate into oxygen atoms, the rms speed becomes:

The root mean square speed of gas molecules at 27°C is v. At what temperature will the rms speed become 2v?

The rms speed of oxygen molecules (M = 32 g/mol) at a certain temperature T is v. If the temperature is doubled and oxygen molecules completely dissociate into oxygen atoms (M = 16 g/mol), what is the new rms speed?

The rms speed of molecules of a gas at temperature T is v. If the temperature is doubled, the new rms speed will be:

A gas molecule at 300 K has an rms speed of 400 m/s. The rms speed of the same gas at 1200 K will be:

The rms speed of oxygen molecules at 27°C is v. At what temperature will the rms speed become 2v?

A star emits maximum energy at wavelength 4000 Å and another star at 6000 Å. The ratio of their temperatures T₁/T₂ is:

Two samples of ideal gas A and B are at the same temperature. The molecular mass of A is twice that of B. The ratio of their rms speeds vₐ/vᵦ is:
