Here is our dose of fascinating trivia from the world of Chemistry for you.

  • Every year on October 23 from 6:02 am to 6:02 pm, chemistry students, and chemists celebrate Mole Day in honour of Avogadro’s number (6.02210^23), the number of carbon atoms in 12 grams of carbon.
  • One bucket full of water contains more atoms than there are bucketfuls of water in the Atlantic Ocean.
  • Although oxygen gas is colourless, the liquid and solid forms of oxygen are blue.
  • The only letter that doesn’t appear on the periodic table is J.
  • Above 4 C, water expands when heated and contracts when cooled. But between 4 C and 0 C, it does the opposite, contracting when heated and expanding when cooled.
