Mystery Molecule

Today’s something a little different … it’s a game. I’m going to list some facts about a particular substance/molecule and you get to guess what they refer to! And if you guess before finishing the post, comment below!

  • This substance is most dense at 277 degrees Kelvin
  • It has at least 2 seperate liquid phases
  • The amount of it has barely changed in Earth’s history
  • There have been 256 recorded conflicts over this since 3000BC
  • Too much of it can be fatal (but really that goes for pretty much anything)
  • 75% of people have a chronic lack of it
  • The US uses the most of this per capita every year
  • There are 8,000,000,000,000,000,000,000,000 (8 septillion) molecules of this in a 200mL sample
  • A total of 200 million hours are spent globally every day to collect this
  • Kangaroo rats can go their entire lives without every ingesting this
  • In its gas form, it is both colourless and odourless
  • In its liquid form, it has very high surface tension (the molecules like to stick together)
  • It is found naturally on Earth in all 3 of its main forms: solid, liquid and gas
  • There is an official day to celebrate it (that’s this Thursday 22nd March!)

 

Have you guessed yet?

It’s actually really common.

It covers 70.9% of Earth’s surface, if that helps; however, we can only use 0.3% of it. We also breath out 240mL of it every day and scientists are trying to figure out if it exists on Mars. It’s pretty much the best solvent ever, as it can dissolve more other substances than anything else we know about. If you haven’t guessed yet, scroll down even further!
