Purpose:To show the different rates of heat conduction in several metals
Description:This demonstration consists of a series of bars of different metals, with temperature-sensitive liquid crystal strips attached to each. When the tips of the bars (and only the tips) are lowered into a beaker of hot water, the liquid crystal strips will change colour at different rats, showing the different rates of heat conduction of the different metals.
Note: Use water no hotter than 90C. Do not expose to open flame, and do not apply water or heat to the liquid crystal strips, and keep them out of direct sunlight.
Loc codes:I2, TBD
