Question

particles of which matter have high speed and why?​

Answer 1

Explanation:

The particles of gases have high kinetic energy and thus, the particles of gases move with high speed because the intermolecular spaces between the particles of gases are more and the intermolecular forces between them are less. Hence, the particles of gases move with high speed.

Answer 2

Explanation:

The particles of gases have high kinetic energy and thus, the particles of gases move with high speed because the intermolecular spaces between the particles of gases are more and the intermolecular forces between them are less. Hence, the particles of gases move with high speed.
