Unit 8 Quiz - Forn A More 15 The freezing point of nitrogen is about \( -210^{\circ} \mathrm{C} \). The freezing point of mercury is about \( 171^{\circ} \mathrm{C} \) higher. What is the approximate freezing point of mercury? Select one: a. \( 39^{\circ} \mathrm{C} \)

To find the freezing point of mercury, we simply need to add 171°C to the freezing point of nitrogen, which is approximately -210°C. So, -210 + 171 equals about -39°C. Mercury freezes at a frosty -39°C, well below the freezing point of water, which is why it’s liquid at room temperature! Now, did you know that mercury isn’t just a whimsical element to look at? It is used in a variety of applications, from thermometers to barometers, giving us essential readings of temperature and atmospheric pressure. Just remember, it’s toxic, so handle it with care!
