Maxwell speed distribution

Maxwell-Boltzmann distribution or commonly known as Maxwell speed distribution, explains the division of the energy levels of the molecules of an ideal gas on the basis of the statistical theory. In 1859, Scottish physicist James Clerk Maxwell established the context for the distribution of molecular velocities for random molecules moving in a closed environment. This theory was generalized in 1871 by German physicist Ludwig Boltzmann. He improvised the theory to express the distribution of energy levels among different molecules.

Suppose we have a macroscopic amount (~ moles) of argon gas in thermodynamic equilibrium at STP conditions. In this case, the velocities of the gas atoms follow the Maxwell and Boltzmann distribution with very good accuracy. Which of the following statements is/are true? Select one or more: a. When heating a gas, the ratio of the average speed of the molecules to the most probable speed increases. b.Heating the gas would lead to a shift of the most probable speed of the momentum distribution to a lower value, while the relative number of high-speed atoms would increase. c. Replacing argon atoms with helium atoms would lead to a momentum distribution in equilibrium, the most probable momentum of which would shift to a higher value and the relative number of high-speed atoms would increase.
