Chapter 12, Problem 40A

To determine

Whether all the molecules or atoms in a liquid have the same speed.

Explanation of Solution

Introduction:

The particles in the liquid move with more freedom than in solids but less than in gas.

The atoms and molecules in the liquid travel with a certain degree of freedom, but move under the influence of other particles. There is a distribution of speeds and hence, all the particles do not move with the same speed.

Conclusion:

All the atoms and molecules do not move with the same speed in liquids.
