Why does molecular speed distribution broaden for gas in a cylinder heated from 300K to 600K?

💡 Explanation

The molecular speed distribution broadens because the Maxwell-Boltzmann distribution dictates that at higher temperatures, the particles possess a wider range of kinetic energies; therefore, variance increases rather than the mean free path changing due to number density alone.
