D) specific weight.

Question

Quizplus · Accepted Answer

The physical quantity that quantifies or provides a measure of how active molecules are on a microscopic level is temperature. Higher temperature means that molecules in a system have more kinetic energy and are thus more active. This is why increasing the temperature can increase the rate of chemical reactions, as there are more collisions between molecules. Density, viscosity, and specific weight are all related to the behavior of fluids, but do not necessarily depend on the activity of molecules.
