Chapter 1.2, Problem 2RQ

Interpretation Introduction

Interpretation: The difference between an observation and a theory needs to be explained.

Concept Introduction:Both,an observation and a theory, plays an important role in chemistry. They are not same. So, it is important to distinguish between observations & theories.

Answer to Problem 2RQ

Observations are essential in the subject chemistry. Chemists use observations to collect as well as record the data. Theory is a group of connected ideas or concepts intended to describe something.  For example: Newton observe the apples fall down from the tree. After this Newton gave a theory that there might be some force, which pull the apples down toward the ground. This theory is known as gravity.

Explanation of Solution

The difference between an observation and a theoryis mentioned below:

Observation	Theory
Something perceived that caused curiosity.	Witnessed over and over always same results.
An equation or statement, which reliably predicts pattern in nature.	The explanation of events or observations.
Attempts to explain “what” happens.	Attempts to explain “why” or “how anything/ somethings happens.
Based on calculations.	Based on inference.
For example: Newton observe the apples fall down from the tree.	For example: After this Newton gave a theory that there might be some force, which pull the apples down toward the ground. This theory is knownas gravity.
