  2. WHAT IS CONDENSATION? It’s the cooling process that changes gas into liquid. It’s the opposite of evaporation.

  4. LOOKING AT THE OUTSIDE OF A GLASS OF ICED WATER… • What has happened ? • Why has it happened ? • What is it called ?

  5. Iced water in a glass: Droplets of w―――― form on the outside of the glass. When water v――――― in the air hits the c――― surface of the glass it condenses into l――――― water droplets. ( liquid, water, cold, vapour )

  6. LOOKING AT THE BREATHINGON A MIRROR… • What has happened? • Why has it happened? • What is it called?

  7. Breathing on a mirror Water v――――― in the breath hits the cold mirror and c―――――――― into water d―――――――. The mirror “steams up”. After a while the liquid droplets on the mirror e―――――――― into the air as water vapour, and the mirror clears. ( droplets, vapour, evaporate, condenses)

  8. LOOKING AT THE DEW ON THE GRASS • What has happened? • Why has it happened? • What is it called?

  9. The dew on the grass • Water v――――― in the a―― hits a cold surface and c―――――――― into water d―――――――. (condenses, air, vapour, cold, droplets)

  10. LOOKING AT THE FROST ON THE TREE • What has happened? • Why has it happened? • What is it called?

  11. The frost on the tree • When temperature is b―――― 0ºC, water v――――― in the a―― hits the cold surface and c――――――― into a t――― white layer of i――. ( condenses, below, ice, air, vapour, thin)
