), the distribution curve would appear as a single vertical line (a Dirac delta function) at the origin (

Here are the conceptual explanations for the common extension questions found in this activity: 1. The Effect of Temperature on the Peak

. At absolute zero, all molecular motion theoretically stops, meaning 100% of the particles have zero speed.

The Maxwell-Boltzmann distribution is given by the following equation:

At very low speeds, very few molecules have exactly zero velocity because kinetic energy is quantized in terms of molecular motion; also, the probability density function ( f(v) \propto v^2 e^-mv^2/(2kT) ) gives ( f(v) \to 0 ) as ( v \to 0 ).
