the freezing point of nitrogen is about - 210°c. the freezing point of mercury is about 171°c higher. what is the approximate freezing point of mercury?
-381°c
381°c
-39°c
39°c

Explanation:

Step1: Identify given values

Freezing point of nitrogen: $-210^\circ\text{C}$; Mercury is $171^\circ\text{C}$ higher.

Step2: Calculate mercury's freezing point

Add the temperature difference to nitrogen's freezing point: $-210 + 171 = -39$

Step3: Match with options

The result $-39^\circ\text{C}$ is an option.

Answer:

-39°C
