A Qualitative Observation is an observation that uses the five senses. sight, smell, hearing, touch, and taste. An example of this would be: "This tree has bright green leaves that have soft bumps on them."

The opposite is a quantitative observation, which is measured in numbers, such as the weight or length of an object. For example, 5 pounds or 100 inches. For instance "The stratosphere begins 40 kilometers above the surface of Earth."

This phenomenon is called cohesion. A water molecule can form four hydrogen bonds; the structure is stable and the intermolecular forces are important, explaining the cohesion of water molecules.
