Which of the following is true according to the kinetic theory of gases? a) molecules move randomly. b) molecules have elastic collisions. c) molecules occupy negligible volume. d) all of the above e) none of the above

Option (D) is the correct answer.

Explanation:

According to Kinetic theory of gases, molecules of a gas move in rapid and random motion. That is, particles are constantly in linear motion.

When these molecules colloid with each other then no energy is gained or lost by them. Also, these molecules occupy negligible amount of volume as compared to the volume of the container in which they are placed.

Moreover, as there is no energy loss taking place so, these molecules of gas undergo perfect elastic motion.

Therefore, we can conclude that all of the above given options are true according to the kinetic theory of gases.

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
