What theory partially explains the observed behavior of gases as described in the gas laws that describes the relationships of pressure and temperature to volume? Its postulates are the following:
A. Gas molecules are in constant, rapid motion, moving in straight lines until they collide with each other or with a solid or liquid.
B. Gas molecules undergo elastic collisions (no energy is lost when they collide).
C. The kinetic energy of gas molecules is directly related to temperature.
D. Gas molecules are very far apart and are negligible in volume compared to the volume of the gas.
E. Gas molecules have negligible attraction between them.
