"Many substances—for example, salt (NaCl) and sucrose—dissolve quickly in water. "
Explain how all or some of the following properties of water are related to the above phenomenon:
•H2O molecules are cohesive; they form hydrogen bonds with each other.
•H2O molecules are adhesive; they form hydrogen bonds with polar surfaces.
•Water is a liquid at normal physiological (or body) temperatures.
•Water has a high specific heat.
•Water has a high heat of vaporization.
•Water’s greatest density occurs at 4°C.
