Explain what happens to the plot if (a) temperature was increased by three-fold, or, separately, (b) all the oxygen molecules atomized into atomic oxygen (decrease in mass)?

The Maxwell-Boltzmann distribution for molecular oxygen at 900 K is shown below (Fig. 1). Explain what happens to the plot if (a) temperature was increased by three-fold, or, separately, (b) all the oxygen molecules atomized into atomic oxygen (decrease in mass)? PLOTTING IS OPTIONAL.
