Question 1 Report
A basic postulate of the kinetic theory of gases is that the molecules of a gas move in straight lines between collisions. This implies that?
Answer Details
The kinetic theory of gases states that the molecules of a gas are in constant motion and move in straight lines until they collide with other molecules or the walls of their container. Therefore, the postulate that the molecules of a gas move in straight lines between collisions implies that collisions between gas molecules are elastic. In other words, no energy is lost during the collision and the total kinetic energy of the system remains constant. Thus, the correct option is "collisions are perfectly elastic." The other options are not directly related to the given postulate.
