PRESENTATION: Temperature measurement requires a device that produces a visible variation of a specific magnitude when heat transfer is produced. For example, in the case of a Galileo thermometer, several buoys of different densities float or sink depending on the temperature of the liquid they are immersed in, which also has the same temperature as its surroundings. The lowest buoy in the floating group is the one that indicates the temperature of the environment.
