The graphs above show Maxwell-Boltzmann distributions for one-mole samples of Ar(g). Graph 1 shows the distribution of particle energies at 600 K. A student predicts that if the samples are combined in an insulated container and thermal equilibrium is attained, then the most probable particle energy will be between the most probable energy in graph 1 and the most probable energy in graph 2. Which of the following is the best justification for the student’s claim?

Achange in the number of neutrons in an atom will change an blank . when the number of protons changes in an atom, a new element will form.
