Question

1. (5) Explain why the total kinetic energy of the sites of a molecule is different than the kinetic energy of the center of mass. (5) Explain why the temperature fluctuates in a simulation with attractive and repulsive potential energy. (5) Compare in magnitude the kinetic energy of a ethanol vapor molecule at 35°C and 103.1 mmHg (the vapor pressure) and a liquid molecule at 35°C and 103.1 mmHg.

Step 1

The total kinetic energy of the sites of a molecule is different from the kinetic energy of the center of mass because the sites of a molecule can have different velocities and directions of motion. The center of mass represents the average motion of the molecule Show more…
