Question: In terms of the kinetic molecular theory, in what ways are liquids similar to solids? In what ways are liquids different from solids?

The kinetic molecular theory, a simple theoretical model, can explain about gas behaviour.

This theory is based on the following postulates or assumptions:

1. Gases are made up of a large number of particles that move randomly and behave like hard, spherical things.

2. These particles move in a straight line until they collide with another particle or a container's walls.

3. The distance between the particles is far less than the size of the particles themselves. As a result, a gas's volume is dominated by empty spaces.

4. No attraction exists between the gas particles or the particles and a container's walls.

Both solids and liquids are made up of atoms, ions, and molecules, with very little empty space between the liquid and solid components. The change in temperature affects the speed of the particles in both the circumstances since the velocity is directly proportional to the temperature.

In the case of a solid, the particles are arranged in a regular pattern, but there is no such pattern in the case of a liquid. As a result, solid particles move very little (only vibration occurs), but liquid particles are free to flow past one another.
