Question
Chapter 2, Problem 5RQ
Summary Introduction
To explain:
The reason why water absorbs a great amount of heat with little increases in its temperature and also determines the name of this property of water.
Introduction:
Water is transparent chemical substances that lack taste, color or odor. They are polar molecules and have a tendency to form a hydrogen bond.
