Question

Which of the following can define molecules in the liquid state?

• A. Molecules vibrating in a fixed position and held in place by strong forces
• B. Molecules can rotate and roll over each other because the forces are moderately strong
• C. Molecules can move anyway in random because there are no forces holding the molecules together
• D. A state of matter which contains only charged particles

Answer 1

The correct option is B Molecules can rotate and roll over each other because the forces are moderately strong

In liquid, particles are loosely bound together by intramolecular forces. Unlike a solid, liquid has no fixed shape but instead has a characteristic readiness to flow and therefore takes on the shape of any container.

Forces between them are moderately strong as compare to solid.

Hence, option $B$ is correct.
