Boltzmann Gas
Boltzmann Gas
At the macroscopic level, the temperature of a substance is a parameter—measured by a thermometer—that indicates how hot or cold the substance is. At the microscopic level, the temperature—according to Ludwig Boltzmann—is a measure of the kinetic energy associated with the disordered motion of the atoms or molecules that constitute the sample. This Demonstration illustrates the relation between atomic motion and temperature in the case of a classical gas (Boltzmann gas) modeled as an ensemble of noninteracting hard spheres. Change the temperature and observe the effect on the motion of atoms or molecules.
