Which of the above can correctly be listed as evidences for the particulate nature of matter?
Answer Details
The evidence for the particulate nature of matter is based on the fact that matter is made up of particles.
- Evaporation and Sublimation are evidence for the particulate nature of matter because they involve a change in state from liquid or solid to gas, without breaking the particles themselves. This shows that the particles in a liquid or solid are not continuous, but rather have spaces between them.
- Diffusion is another evidence for the particulate nature of matter. It is the movement of particles from an area of high concentration to an area of low concentration. This shows that particles are constantly in motion, and that they have kinetic energy.
- Brownian motion is also an evidence for the particulate nature of matter. It is the random movement of particles suspended in a liquid or gas. This motion is caused by the collision of the particles with each other and with the molecules of the medium. Brownian motion shows that particles are constantly moving, and that they interact with each other.
Therefore, the correct option is:
- l, ll, lll and lV, which means that all the given processes are evidences for the particulate nature of matter.
