Thermal insulation

Product No: P1043660

Principle

A quick loss of heat is sometimes not wanted. What can be done to keep the temperature in a vessel
constant?

Tasks

Measure the cooling of hot water in two different environments:

In a glass beaker that is fitted out with thermal insulation in the form of felt sheets and is in a second
glass beaker that has a lid, the whole of which is named the calorimeter in the following.
In the same glass beaker but without the thermal insulation.
