3.5 Kinetic Molecular Theory

In examining the Maxwell-Boltzmann distribution curves at different temperatures on the graph below, which variable in the graph remains the same?

This question is about the Maxwell–Boltzmann distribution of molecular energies in a sample of a gas shown in the figure below.

What does the area under the curve represent?

Which of the following pairs of Maxwell–Boltzmann distribution curves best represents the distribution of kinetic energy for particles at two different temperatures?

Note: dashed line = higher temperature, solid line = lower temperature.
