the correct option.​

Answer 1

Answer:

1)surface water - rain water

2)free-flowing liquid - water vapour

3)evaporation -transpiration

5)chemical change - physical process

6)saline water -freshwater

7)Hepatitis A virus - bacteria salmonella typhi

Answer 2

1. Rainwater is the purest form of water.

4. Stirring the solution increases the solubility of the solute in the solvent.
5. The formation of a solution is a physical process.
6. Fresh water is fit for consumption.
7. Typhoid is caused by Salmonella typhi bacteria. Or Hepatitis A is caused by Hepatitis A virus
8. Ozonation is the process of sterilizing water from ozone.
9. Reverse Osmosis is a method of water purification in which water is forced out of the waste through a semipermeable membrane by applying pressure.
10. Purified water is used for preparing solutions for medicinal purposes.
