Chemistry
Answer
The main postulates of kinetic theory of matter are:
- Matter is composed of very small particles called atoms and molecules.
- The constituent particles of a kind of matter are identical in all respects.
- These particles have spaces or gaps between them which are known as inter-particular or inter-molecular spaces.
- A force of attraction exists between the particles of matter which holds them together known as interparticular or intermolecular force of attraction.
- Particles of matter are always in a state of random motion and possess kinetic energy which increases with an increase in temperature and vice-versa.
