Question

Mention and explain a simple experiment to show that the molecules of solids are closely packed and the molecules of liquid are loosely packed.

Answer 1

Explanation:

The particles in a solid are closely packed together. There are so close together that they can only vibrate in a fixed position. When the particles in a solid are heated, the solid melts into a liquid and changes into a gas as well. The particles are not as closely packed together so there is a small amount of space.
