cooling curve

Cooling curve Two temperature sensors can collect some interesting information about cooling during a change of state. In this experiment the temperature of a water bath increases as a substance cools. But the unusual...

insulation of stacked cups

Three plastic cups are stacked inside each other and a temperature probe placed between each cup. Before stacking the final cup hot water (take care) is poured into the middle cup. Quickly stack the...

insulation

You can use a temperature sensor to study the insulating properties of materials. Two temperature sensors allow you to compare different materials at the same time. In this example two beakers of hot water...
