Because Mercury expands in heat, it is more accurate than other elements used in thermometers.

The capillary tube of the thermometer ( in case of a mecury thermometer).
It is a thermometer, and is used to show the temperature.
The Mercury expands with temperature. Since expansion is linear over the normal range of a mercury-driven thermometer, the level of mercury within a little glass tube indicates the current temperature of the thermometer's immediate environment.

what do they use for the liquid in glass ball thermometer
It could be used to do this - it is capable of doing it. However, Mercury is poisonous and a mercury thermometer is made out of fragile glass. Thus the danger that the thermometer would break releasing mercury into the milk (which would be for a person to drink) means that a mercury thermomiter is not the temperature sensor to use in this instance.
It can easily be seen, it expands quickly, it does not stick on the glass, it can easily be seen
German physicist Daniel gabriel Fahrenheit invented the mercury-in-glass thermometer
In a mercury thermometer, a glass tube is filled with mercury and a standard temperature scale is marked on the tube. With changes in temperature, the mercury expands and contracts, and the temperature can be read from the scale. Mercury thermometers can be used to determine body, liquid, and vapor temperature.
