The energy of a given sample of an ideal gas depends only on its

As we know that kinetic energy of ideal gas is given by

Where K. E=kinetic energy of gas

k_B = Boltzmann constant

T = temperature of gas

Since k_B is a constant therefore, kinetic energy of gas is proportional to temperature of gas.

A gas behaves more closely as an ideal gas at

The pressure of an ideal gas is written as Here E refers to

Which of the following gases has maximum rms speed at a given temperature?

Figure shows graphs of pressure vs density for an ideal gas at two temperatures T₁ and T₂.
