Consider the following statements :
- 1Particles of matter intermix on their own.
- 2Particles of matter have force acting between them.
Which of the statements given above is/are correct?
General KnowledgePhysics
- A1 only
- B2 only
- CBoth 1 and 2
- DNeither 1 nor 2
Explanation
Both are foundational tenets of the particle/kinetic theory of matter: particles intermix spontaneously (diffusion — e.g., ink in water), and particles exert interparticle forces of attraction and repulsion on each other. Neither statement contradicts standard physics. Hence both statements are correct.
