Key Info
  • Changing state - water and dissolved minerals
  • Duration: 01:44
  • An experiment to demonstrate how minerals dissolve in water and a look at which minerals and metals are found in different types of water. Water is poured into a flask and we see what happens when it starts to boil. As the water heats up it starts to evaporate. The gas travels out of the flask and into a cold tube. The water vapour condenses and drops out as a liquid. The scientist is then able to look at the minerals contained in the sample of water and explains how minerals are dissolved in water as it flows through the ground.
