A change of state between solid and liquid can be caused by adding or removing heat (ACSSU046)

Elaborations
  • investigating how liquids and solids respond to changes in temperature, for example water changing to ice, or melting chocolate
  • exploring how changes from solid to liquid and liquid to solid can help us recycle materials
  • predicting the effect of heat on different materials
ScOT terms

How is the melting of ice affected by heat?

Investigate how heat affects the melting process. Place ice cubes into a container and time how long they take to melt. Repeat the experiment with the container wrapped in wool, and observe the difference in the state of the ice after the given time. Complete the data table and then use the findings to answer the conclusion ...
