Why is it important to always use the correct number of significant figures when solving a problem

By using significant figures, we can show how precise a number is. If we express a number beyond the place to which we have actually measured (and are therefore certain of), we compromise the integrity of what this number is representing.

Why is it important to use the correct number of significant figures when expressing measurements averages and uncertainties?

The number of significant figures that should be used in stating a result is inseparably connected with the accuracy with which the result is known. ... But the apparatus can measure only up to a precision of one place after the decimal. Hence the correct way to express the answer is 2.4 ± 0.2.

Explanation:

when atmosphere interacts with biosphere they focuses on on the sources and sinks of green house gases (ghgs) air pollutants, particular matters, water and energy between the earth's surface and the atmosphere. the biosphere affects the climate. the atmosphere and biosphere are in constant interaction with each other, and all living things rely on gases in the atmosphere for life. organisms such as animals take in oxygen gas form the atmosphere to use in every cell of their body for smooth functioning of daily routine exercises.
