Unit 13 - Temperature Effects
Learning Outcomes:
- investigate and describe the expansion of solids, liquids and gases when heated, and contraction when cooled (OP23)
- demonstrate the expansion of water on freezing (OP24)
- carry out experiments that involve changes of state from
i. solid to liquid and liquid to solid
ii. liquid to gas and gas to liquid (OP28)
Expansion of solids experimentThe ball and ring experiment
Expansion of liquids experimentOr is it the gas that is expanding ? how would you make it better ?
Freezing water expandsIf you try this at home put the bottle in a plastic bag first to catch the bits

Expansion of gases experimentShowing expansion and contraction on heating and cooling
The bimetallic strip (extension)A practical use of the expansion of solids
Exploding water pipes !Do NOT try this at home !!!
