Q. Water freezes at

0^{\circ}

Celsius. Four friends test the temperature of their water.

\newline

Miko's water is

3^{\circ}

Celsius.

\newline

Ana's water is

-8^{\circ}

Celsius.

\newline

Rocky's water is

4^{\circ}

Celsius.

\newline

Leon's water is

-1^{\circ}

Celsius.

\newline

Which friend's water has a temperature closest to the freezing point?

\newline

Choose

1

answer:

\newline

(A) Miko

\newline

(B) Ana

\newline

(c) Rocky

\newline

(D) Leon

Find Closest Temperature: We need to find out which temperature is closest to $0^\circ\text{C}$ , the freezing point of water. We will compare the absolute differences between each friend's water temperature and $0^\circ\text{C}$ .
Calculate Absolute Differences: Miko's water is at $3^\circ\text{C}$ . The absolute difference between Miko's water temperature and the freezing point is $|3^\circ\text{C} - 0^\circ\text{C}| = 3^\circ\text{C}$ .
Compare Absolute Differences: Ana's water is at $-8^\circ\text{C}$ . The absolute difference between Ana's water temperature and the freezing point is $\left|-8^\circ\text{C} - 0^\circ\text{C}\right| = 8^\circ\text{C}$ .
Identify Smallest Difference: Rocky's water is at $4^\circ\text{C}$ . The absolute difference between Rocky's water temperature and the freezing point is $|4^\circ\text{C} - 0^\circ\text{C}| = 4^\circ\text{C}$ .
Identify Smallest Difference: Rocky's water is at $4^\circ\text{C}$ . The absolute difference between Rocky's water temperature and the freezing point is $|4^\circ\text{C} - 0^\circ\text{C}| = 4^\circ\text{C}$ .Leon's water is at $-1^\circ\text{C}$ . The absolute difference between Leon's water temperature and the freezing point is $|-1^\circ\text{C} - 0^\circ\text{C}| = 1^\circ\text{C}$ .
Identify Smallest Difference: Rocky's water is at $4^\circ\text{C}$ . The absolute difference between Rocky's water temperature and the freezing point is $|4^\circ\text{C} - 0^\circ\text{C}| = 4^\circ\text{C}$ .Leon's water is at $-1^\circ\text{C}$ . The absolute difference between Leon's water temperature and the freezing point is $|-1^\circ\text{C} - 0^\circ\text{C}| = 1^\circ\text{C}$ .Now we compare the absolute differences: Miko's is $3^\circ\text{C}$ , Ana's is $8^\circ\text{C}$ , Rocky's is $4^\circ\text{C}$ , and Leon's is $1^\circ\text{C}$ . The smallest absolute difference is Leon's, which is $1^\circ\text{C}$ .
