Question
Chapter 1, Problem 1.11P
Interpretation Introduction
Interpretation:
The reason should be explained for the more usefulness of qualitative observation than a non-quantitative observation. Whether the following observations are quantitative or not should be identified.
- The Sun rises in the east.
- A person weighs one-sixth as much on the Moon as on Earth.
- Ice floats on water.
- A hand pump cannot draw water from a well more than 34 ft. deep.
Concept Introduction:
An observation which can be counted / measured or results in any numeric is known as quantitative observation. For an example: number of moles, molarity etc.
An observation which can be observed but can’t be measured is known as non-quantitative observation. For an example: color of sample, texture of sample etc.
