Question

which of these is a postulate of kinetic molecular theory? a the kinetic energy of gas molecules depends on temperature. b collisions between gas molecules are inelastic. c molecules of gases attract and repel one another. d molecules of gases have a finite volume.

Explanation:

One of the postulates of kinetic - molecular theory is that the average kinetic energy of gas molecules is directly proportional to the absolute temperature. Collisions between gas molecules are elastic in this theory, gas molecules do not attract or repel one another (in an ideal - gas scenario), and gas molecules are considered to have negligible volume.

Answer:

A. The kinetic energy of gas molecules depends on temperature.
