1. Water is an important part of our diet.

$\Large \mathfrak{ \underline{ \green{Reason}}}$

Water is an important part of all body functions and processes, including digestion and elimination. When you're on a diet, water also acts as a weight-loss aid because it can help you eat less. "Drinking water is important during weight loss because it provides hydration without unwanted calories."

2. Water present in oceans and seas is saline.

$\Large \mathfrak{ \underline{ \green{Reason}}}$

Salt in the sea, or ocean salinity, is mainly caused by rain washing mineral ions from the land into water. Carbon dioxide in the air dissolves into rainwater, making it slightly acidic. Isolated bodies of water can become extra salty, or hypersaline, through evaporation. The Dead Sea is an example of this.

3. The aquatic animals and plants are able to survive in colder regions.

$\Large \mathfrak{ \underline{ \green{Reason}}}$

This anomalous property of water enables aquatic plants and animals to survive in colder regions of world because even when the water of ponds, lakes, river freezes it freezes on the top but remains a liquid below ice layer.

4. Glass bottles when filled completely with water break when kept in the freeze.

$\Large \mathfrak{ \underline{ \green{Reason}}}$

A glass bottle completely filled with water should not be kept in a freezer because the bottle can break and result in damage. We know that water expands after freezing and if acompletely water filled glass bottle is placed in freezer, the water would freeze and would expand resulting in the bottle to break.

$\Large \mathfrak{ \underline{ \purple{Statement}}}$

5. Steam causes more severe burns than boiling water.

$\Large \mathfrak{ \underline{ \green{Reason}}}$

Steam will produce more burn than boiling water since steam has more warmth vitality than water because of its dormant warmth of vaporization. This is because steam contains the heat energy of boiling water (as steam is formed from boiling water) along with latent heat of vaporisation.

6. We should drink 3 - 4 liters water daily.

$\Large \mathfrak{ \underline{ \green{Reason}}}$

Not getting enough water can be detrimental, potentially causing side effects like nausea, fatigue, constipation, headaches, and dizziness ( 4 ). Therefore, drinking 3 liters (100 ounces) of water per day may help youmeet your hydration needs to support better health.

$\Large \mathfrak{ \underline{ \purple{Statement}}}$

7. Water is known as "Universal Solvent".

$\Large \mathfrak{ \underline{ \green{Reason}}}$

Water is called the "Universal Solvent" because it is capable of dissolving more substances than any other liquid. This is important to every living thing on earth. This allows the water molecule to become attracted to many other different types of molecules.

$\Large \mathfrak{ \underline{ \purple{Statement}}}$

8. Purification of water is important before consuming it.

$\Large \mathfrak{ \underline{ \green{Reason}}}$

Water purification method is needed to remove germs, bacteria, lead, mercury and pollutants from water. These contaminants can be removed through various techniques used topurify drinking water. The system helps to remove impurities that may enter drinking water.

9. Potash alum is added to water in the loading tank and is allowed to stand for sometime.

$\Large \mathfrak{ \underline{ \green{Reason}}}$

The process is called loading in which potash alum or chrom alum is put in a solution of muddy water and alument angles the particles of mud around it and eventually becomes larger and in this way,loading takes place and mud particles and water are separated but this process is not very efficient and filtration is used.

$\Large \mathfrak{ \underline{ \purple{Statement}}}$

10. Oil spill from oil tankers causes death of aquatic animals.

$\Large \mathfrak{ \underline{ \green{Reason}}}$

Oil spills are fatal to most of marine organisms because they drain oxygen from the sea and thus destroys the plant and animal world in it. Many birds and marine organisms are trapped in oil spillages on the shores, and then they die because of their inability to breathe or oil poisoning.
