The correct option is
B liquid dispersed in gas
Explanation for the correct option:
Option(B): liquid dispersed in gas
- A colloid is known as a mixture in which one species, having a size a little more than microscopic, is dispersed in a continuous phase.
- Here, the species that is dispersed is called the dispersed phase, whereas the one that gives the continuous phase is called a dispersion medium.
- In the case of clouds, it has a dispersion medium as gas whereas the dispersed phase is the liquid.
- Hence it can be said that a cloud is an example of a liquid dispersed in a gas.
Explanation for the incorrect option:
Option(A): Solid dispersed in gas
- In the case of solid dispersed in a gas, the dispersion medium can be given as gas whereas the dispersed phase is solid.
- Aerosol is an example of a solid dispersed in gas.
- The solid dispersed in gas doesn't include Cloud as an example.
Option(C): Liquid dispersed in solid
- In the case of liquid dispersed in solid the dispersion medium can be given as solid whereas the dispersed phase is liquid.
- Examples of gel include: cheese, butter, and jellies.
- liquid dispersed in solid does not correspond to the example of Cloud.
Option(D): Solid dispersed in liquid
- In the case of solid dispersed in a liquid, the dispersion medium can be given as liquid whereas the dispersed phase is solid.
- Sol can be represented as a colloidal suspension with solid dispersed in the liquid.
- The solid dispersed in the liquid doesn't include Cloud as an example.
Hence, Cloud is an example of liquid dispersed in gas.
