Given below are two statements: Statement-I : Smoke, dust, fog and clouds are examples of aerosol Statement-II : If gas is dispersion medium then sol is known as aerosol. In the light of the above statements, choose the most appropriate answer from the options given below:
Options
- ABoth statement I and statement II are incorrect.
- BStatement I is correct but statement II is incorrect
- CStatement I is incorrect but statement II is correct.
- DBoth Statement-I and statement-II are correct.
Correct answer
B. Statement I is correct but statement II is incorrect
Step-by-step solution
Statement-I: Smoke, dust, fog, and clouds are examples of aerosol. This statement is correct. Aerosols are fine solid particles or liquid droplets suspended in a gas, and all the mentioned examples fit this definition. Statement-II: If gas is the dispersion medium, then sol is known as aerosol. This statement is incorrect. In a sol, the dispersion medium is a liquid, not a gas. When a solid is dispersed in a gas, it is typically referred to as an aerosol. So, while aerosols do have a gas as the dispersion medium, a
