HEATING AND COOLING CURVE OF WATER
INDIVIDUAL WORK (should be done under strict supervision)
write a selectie report which must include the following:
32
Apparatus
Method (This should be a description of what you did it should not be a
copy of the method on the worksheet provided to you)
Observations and Recording of results (Use the results recorded when
conducting the expenment)
Analysis and interpretation of results and observations
Use the graph paper provided to plot two graphs of temperature
against time on the same set of axes, to represent the data obtained
when ice is heated to boiling point and hot water is cooled down
Winte down the little of the graphs
Label each graph appropriately as "Heating curve' and Cooling
cune"
Also indicate the phases of water on the heating curve
