Q. The freezing point of pure water is

0 \, ^{\circ}\mathrm{C}

, but adding salt to water changes its freezing point. During a science experiment, Patrick finds a solution of salt water that has a freezing point of

-6 \, ^{\circ}\mathrm{C}

.

\newline

Which of these describes the freezing point of the salt water?

\newline

(A) colder than pure water's freezing point

\newline

(B) warmer than pure water's freezing point

Identify Freezing Points: Identify the freezing point of pure water and the freezing point of the salt water solution. Pure water freezes at $0 \, ^{\circ}\mathrm{C}$ , and the salt water solution freezes at $-6 \, ^{\circ}\mathrm{C}$ .
Compare Temperatures: Compare the two temperatures to determine which is lower. Since $-6 \, ^{\circ}\mathrm{C}$ is less than $0 \, ^{\circ}\mathrm{C}$ , the salt water solution has a lower freezing point than pure water.
Choose Correct Answer: Choose the correct answer based on the comparison. The correct choice is (A) colder than pure water's freezing point, because $-6 \, ^\circ\mathrm{C}$ is indeed colder than $0 \, ^\circ\mathrm{C}$ .
