Question

Particles in liquid and gases show random motion. What does it mean and why this occur???

Answer 1

Explanation:

Brownian motion or pedesis is the random motion of particles suspended in a fluid resulting from their collision with the fast-moving molecules in the fluid. This pattern of motion typically alternates random fluctuations in a particle's position inside a fluid sub-domain with a relocation to another sub-domain. 

Answer 2

Answer:

Particles in liquid and gases show random motion.

Explanation:

It means that the particles in liquid and gases state do not show a fixed pattern of movement and are random in motion.

In solid the molecules are tightly packed whereas in liquid molecules are less tightly or loosely packed and in gases molecules are freely moving.

So they will move with high speed or say velocity in the empty space available in the container and due to their high velocity they collide with each other hence forming a random  motion.

That is why it is said that liquid and gases show random motion.
