Question

Why do gases show a random motion by moving in all directions?

Answer 1

Step-1:

Gases:

Gases have neither a fixed shape nor a fixed volume. Hence, they do not have fixed boundaries. They can flow in all directions and can be easily compressed. In a given space.

Example of Gases :

Air, oxygen, carbon dioxide, steam

Step-2:

Gases show a random motion by moving in all directions:

1. The number of particles in gases is less than that in solids and liquids.
2. The constituent particles of gases have maximum kinetic energy because of the presence of large inter-particle spaces between them and therefore, they show a random motion by moving in all directions.
