1.A healthy people should drink at least 7-8 glasses of water a day (about 2.5liters) when day is hot we need to drink more water so each day we should drink 2000ml-2500ml
2.If we drink too less of water the body of waste metabolism does not go out affecting the health of body

Why we need to drink 8 cups of water a day ?
1. Urination: And amount of urine discharged the day of about 1500ml

2. Sweating

3. Respiration

Reactant is someing that can all other reactant to it and combine to something different such as water is combine by two hydrogen and one oxygen (HO) and water is a reactant too so it can combine to other stuff too such as Co2+H2O=H2CO3
(Carbon+Oxygen2)
+
(Hydrongen2+Oxygen)
=
(Hydrongen2+Oxygen3)
And downthere  is the example of reactant combine :

1.)High specific Heat
-water absorbs a great deal of heat for every molecule of water present because of the large amount of Hydrogen Bonds.
2Water is a polar molecule it allow to dissolve any other polar molecule because it have both posstive charged and negative charged
3)the ph value is 7 .It is neutral
