Question

dr. kelvin makes three chemical mixtures in his lab. he records the temperatures of these mixtures in the table.
chemical mixture | temperature (°c)
mixture a | -5
mixture b | 2
mixture c | -3
which mixtures temperature is closest to zero?
mixture a
mixture b
mixture c

Explanation:

Step1: Find absolute - values

Find the absolute value of each temperature. The absolute value of a number $x$, denoted as $|x|$, gives the distance of $x$ from zero on the number line.
$| - 5|=5$, $|2| = 2$, $| - 3|=3$

Step2: Compare absolute - values

Compare the absolute values $5$, $2$, and $3$.
We know that $2<3<5$.

Answer:

Mixture B
