Tuesday, April 14, 2009 ; Science Notes - Water Cycle
Dear 5 Diligence,
These are the Science Notes on Water Cycle. I have also sent it to your LEAD e-mail. I cannot attach the table, so please refer to your e-mail (:
Water Cycle
(Ice)
Solid
(Water)
Liquid
(Water Vapour)
Gas
Solid to Liquid – Melting (Heat gain) The surrounding or environment loses heat.
Liquid to Gas – Evaporation or Boiling (Heat gain) The surrounding or environment loses heat.
Gas to Liquid – Condensation (Heat loss) The object where the water vapour condenses on gains heat.
Liquid to Solid – Freezing (Heat loss) The surrounding or environment gains heat.
Heat Transfer:
- Heat gain
- Heat loss
-Energy can never disappear.
-Water becomes gas when boiling.
-Cold temperature slows down evaporation.
-Liquid does not condense.
Steam = Hot water vapour

Great notes, Cassilda. I hope the class appreciates your efforts.
For the rest of you, do take note that it is important to know the concept of condensation thoroughly.
If you have any questions regarding condensation, please post it in the blog. It will benefit everybody.
Mr Wan, i dun get why water can evaporate in fridge though, theres nothing hot in it to make it evaporate right? this is about evaporation, not condensation,,, XP soz...
YUN LING HERE BTW!!!
if u say u already answered that, i dun understand a thing. very sorry.
