Internal processes plain to see

The highly responsive temperature sensors in conjunction with the well tested MGA software can make internal processes plain to see, something that has hitherto been impossible with conventional measuring instruments. For instance, if hot and cold water are brought into contact, the way the temperature evens out depends on which of the liquids is inside and which is on the outside.

Heat of evaporation

The experiment set has the equipment to investigate factors favouring evaporation and to demonstrate that the heat of evaporation by far the greatest contributor to the cooling process, followed by apart from thermal conduction, convection and radiation.

The phenomenon of supercooling

The experiment set not only allows the melting curve of ice and the freezing curve of water to be recorded, it also allows the phenomenon of supercooling to be demonstrated. When this happens water can stay liquid down to a temperature as low as -5°C.
