The principle is the proportional dilatation of mercury with temperature.
Liquids expands on heating and contracts om cooling , when it expands it gives the reading
to tell old people that have a mercury thermometer what the temperature is
WORKING: Place the bulb of the thermometer filled with mercury in a vessel ov small pieces of ice the mercury will arise in the tube and will come to rest at a certain point.this point shows the melting point of ice. CONSTRUCTION:A thermometer consists of a glass bulb filled with mercury.A cappilary tube arises from this bulb.Due to the narrow bore of the tube a small change in the volume of the mercury becomes significiantly visible.
If the liquid in a thermometer is red it is not mercury, it is alchohol which has been colouired.

capillarity rise.heating expands mercury whereas cooling contracts mercury

A mercury thermometer is used to measure temperature.
A clinical thermometer will offer more precise calibrated readings than a mercury thermometer. The range of measurable temperature differs between a clinical and a mercury thermometer with the mercury thermometer having the wider range.

Mercury the liquid inside thermometer is mercury.. but it is called thermometric liquid.
If the liquid in a thermometer is red it is not mercury, it is alchohol which has been colouired.
Most pool thermometers do not contain mercury. An easy way to tell if a pool thermometer contains mercury is if it sinks to the bottom of the pool rather than float.
