44. The unique property of water molecules is

(a)  Universal solvancy

(b)  Conductivity

(c)   Specific heat

(d)  Ability to maintain body temperature

Ans.       (a)  When a substance is put in water, its individual molecules or ions seperate from one another and mix with water molecules. The partial electrical charges of polar water molecules are attracted to charged ions and to partially charged polar molecules, so that water readily surrounds and dissolves these solutes.
