because the mixture of ice and water has an equilibrium temperature of 0 C and thus it will be the first calibration system and making sure that thermometer is working properly. The thermometer will have better contact with the water than with lumps of ice and therefore adjust better to its temperature.
In theory water can be used, but it expands to a gas and would burst the thermometer above 100 0 C. Similarly, when water freezes at 0 0C it expands unlike other materials and would also break the thermometer. The useful range of the water thermometer would thus be limited.
if you put water in a thermometer and it gets hot the water expands and might and burst and when it gets to cold it freezes
Mercury is a good conductor of heat and it expands to certain levels when heated to certain temperatures.
The first thermometer was a tube filled with water and air.
We still use colored alcohol for our liquid in everyday thermometers.

The question must be asked carefully. If the thermometer is in water ice and there is no liquid water, and there is one atmosphere of pressure, the thermometer can read anything from the freezing point of water and lower, depending on the range of the thermometer. If the thermometer is in a stable mix of water and ice, it will read the freezing point of water.
the liquid in the thermometer rises because of the surrounding heat which causes a chemical reaction wihtin the substance which makes the liquid rises. When, the liquid sinks, itn is because the air has gotten cooler
The first thermometer was a tube filled with water and air.
The liquid commonly used in a thermometer is mercury or COLOURED ALCOHOL.
Water - Galileo Galilei invented a rudimentary water thermometer in 1593 which, for the first time, allowed temperature variations to be measured
We still use colored alcohol for our liquid in everyday thermometers.
it is used in liquid form as in room temperature the mercury is in liquid
Water Temperaure cools
A thermometer is used to measure air temperature, or the temperature within a solid or liquid.
Mercury
iodine and Mercury
water doesnt undergo significant thermal expansion. alcohol expands more when it's heated
mercury
A laboratory thermometer is used to check the temperature, or changes in temperature, of an object with precise accuracy.
