Question

In solids, the atoms are free to move around unlike gases.

• A. True
• B. False

Answer 1

The correct option is B False

1. In solids, the particles are closely packed.
2. There is a strong force of attraction between holds them together in fixed positions.
3. Thus, the positions of particles in a solid are fixed.
4. The particles of a solid only vibrate about their fixed positions. They cannot move from one position to another.
5. Because of this, molecules of the solids have the least kinetic energy.
6. Due to this, solids have the most orderly arrangement of particles.
7. But, in gases, the particles are free to move around.

Hence, the given statement is false.
