Mercury Compared to Water

Mercury Compared to Water This is going to be a short post because I’ll be comparing Mercury to Water. I’ll be trying to find out why mercury is 14 times denser than water: I poured all of my mercury into a petri dish and I have 22.70 grams of it. So I added the same weight of water into a petri dish and weighed it. And after that, I pour the mercury and water into beakers to measure them. There are 1.6 ml of mercury and 22 ml of water. That explains why mercury is 14 times denser than water (22 ÷ 1.6 = 13.75 ≈ 14). Here are some more comparisons:  Mercury  Water Color  Metalic Silver  Clear/Transparent Density  13.534 g/cm3  1 g/cm3 Conductivity  High  Medium Toxicity  High  None   Advertisements

Making a Mercury Switch

Making a Mercury Switch Remember that experiment about mercury? I tried to show you that mercury can conduct electricity. And it did. I studied it a little bit more and I found this: A Simple (Tilt) Mercury Switch: It’s similar to the one we did the last time. Instead of tilting it around, what if you suck the mercury in […]

Does Mercury Conduct Electricity?

Does Mercury Conduct Electricity? I bought this from my science shop yesterday so that I could perform more experiments. Why is it a liquid? The reason for mercury being a liquid is complex. It is heavy; a chunk of iron can float on mercury. Compared to other metals, it does not conduct heat well. However, it conducts electricity fairly well. Mercury is the only metal that is a liquid at normal […]
