Which of the following is true of liquids? a. they have less kinetic energy than solids, gases, and plasmas. b. they have slightly less kinetic energy than solids, but more kinetic energy than gases or plasmas. c. they have slightly more kinetic energy than solids, but less kinetic energy than gases or plasmas. d. they have more kinetic energy than solids, gases, and plasmas.?

Option (c) is the correct answer.

Explanation:

In solids, the molecules are more closely packed together due to greater inter-molecular forces of attraction between them. As a result, molecules do not have kinetic energy and they have definite shape and volume.

Whereas in liquids, molecules have more kinetic than molecules of a solid. Therefore, liquids are able to move from their initial position and they acquire the shape and volume of a container in which they are kept.

On the other hand, gases have more kinetic energy than solids or liquids. As a result, they move randomly from one place to another. And plasma is a hot ionized gas in which molecules collide more vigorously with each other as they contain positively charged ions and negative electrons.

Hence, we can conclude that it is true of liquids that they have slightly more kinetic energy than solids, but less kinetic energy than gases or plasmas.
