As a gas is heated, how does the distance between the particles of the gas affect its ability to transfer sound?

In gases, temperature relates to its kinetic energy - the hotter the gas, the faster the particles will move (for example, if we take that the formula of kinetic energy is Ek = 3/2 * k * T where k iz Boltzmanns constant and T is temperature, we see that kinetic energy - which is the energy an object has when its moving - only really depends on the temperature.)
