Required Practical 2: Thermal Insulation (Physics Only)

The four factors affecting rate of heat transfer are:
Thickness
Layers
Conductivity of material
Colour/Lustre

Investigate one of the four factors which affect the rate of heat transfer.
Allow hot water to cool.
Measure the temperature of the water with a thermometer at set time intervals.
Measure time with a stopwatch.
Plot a graph of temperature against time, (we call these cooling curves.)
The steepest gradient is the highest rate of heat transfer.
