: The shape and peak position (most probable speed) remain the same, but the total area under the curve doubles. This is because the area represents the total number of particles in the sample.
$$v_p = \sqrt\frac2kTm$$
As temperature increases, the peak of the curve shifts to the (higher average speed) and becomes shorter/wider (flattens) to maintain the same total area. Molar Mass (MM): At the same temperature, lighter gases (lower MM) have a wider, flatter : The shape and peak position (most probable
