Answer to Question 1

Water naturally occurs in all three strates on the Earth; the covalent bonds of hydrogen and oxygen are difficult to separate; the nature of the hydrogen-oxygen bond gives the hydrogen side of water molecule a positive charge and the oxygen side a negative charge. This polarity results in water molecules attracting to one another (cohesion). Water also attaches to other substances (adhesion). Water is also able to dissolve many substances. Water has high surface tension and capillarity. When water cools, it contracts and increases in density until it reaches 4C (39F), below which it expands and becomes less dense. Etc.

Answer to Question 2

TRUE
