Question

mercury, a chemical element formerly used in most thermometers, freezes at -38°f. which of these describes the temperature at which mercury freezes? below 0°f at 0°f above 0°f

Explanation:

Step1: Analyze the given temperature

The freezing - point of mercury is given as $- 38^{\circ}F$.

Step2: Compare with 0°F

Since $-38 < 0$, the temperature $-38^{\circ}F$ is less than $0^{\circ}F$.

Answer:

below 0°F
