Q.2.85 - An Introduction to General, Organic, and Biological Chemistry

Question

State the temperature on the Celsius thermometer to the correct number of significant figures: (2.3)

Step-by-Step Solution

Answer

The temperature is $61.5^{o}C$

Step 1: introduction

According to the thermometer portrayed in the figure, every division addresses a one-degree change in temperature. From the figure, it is known with the assurance that the temperature lies somewhere in the range of $61-62$degrees.

Step 2: explanation

Since it shows up someplace somewhere between the two, the temperature can be accounted for as $61.5^{o}C$.

The numbers $6$ and $1$ are sure, while the number $5$ is a guess.

Hence significant figures are certain digits $+$estimated digits

$2+1=3$

significant figures are $3$
