Is Maxwell's Distribution Law Applicable to High Speed Particles?

Click For Summary
SUMMARY

The Maxwell Distribution Law, which describes the velocity distribution of gas particles, is not applicable to high-speed particles approaching the speed of light, such as protons and positrons. This law operates under the assumption of non-relativistic conditions, specifically E = p²/2m, which holds true for electrons and protons at reasonable temperatures. Even in extreme environments like the center of the sun, particle velocities remain non-relativistic until temperatures reach billions of degrees Kelvin, at which point modifications to the Maxwell distribution become necessary.

does maxwell distribution law of velocity of gas also applicable for very high speed near to speed of light? means can we apply this law to particles like proton, positron?

No, it assumes E = p^2/2m. But this is true even for electrons and protons as long as the temperature is reasonable. Even at the center of the sun the velocity of the electrons and protons is non-relativistic. You need to reach billions of degrees K before relativistic corrections come into play. At these temperatures the Maxwell distribution needs to be modified.
