Problem
A rigid 2.0 L container holds an ideal monatomic gas initially at 300 K. The container is slowly heated to 450 K while the volume remains constant.
Boltzmann constant kB=1.38×10−23J K−1.
(a) Describe qualitatively how the shape and position of the Maxwell–Boltzmann distribution of molecular kinetic energies in the gas change as the temperature is raised from 300 K to 450 K.
(b) Using appropriate reasoning, determine the percent change in the average kinetic energy of a single gas particle that accompanies the temperature increase.
(c) Explain why the mass of the gas particles does not affect the relationship you determined in part (b).
