what do they use for the liquid in glass ball thermometer
The capillary tube of the thermometer ( in case of a mecury thermometer).
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.
-200 to 600 degree centigrade
When placed in boiling water, the materials comprising the thermometer respond in the order in which the heat penetrates them. As the heat first permeates the glass cylinder, the cylinder expands, enlarging the bore. For the moment until the mercury is also heated, the constant volume of mercury fills the expanded bore to a slightly lower depth. When the heat reaches the mercury and it also expands, its volume to increase, and the liquid depth rises in the bore.
Mercury is poisonous.

mercury
German physicist Daniel gabriel Fahrenheit invented the mercury-in-glass thermometer
The capillary tube of the thermometer ( in case of a mecury thermometer).
Temperature Sensor
The red liquid in a thermometer is Mercury, which is usually encased in a glass tube
The sensor is just the mercury, a liquid metal.
For a classic thermometer: glass and mercury, colored ethanol or another liquid.
"thermal expansion"
either mercury or alcohol
There is nothing else in a mercury thermometer. However, some similar (glass tube-type) thermometers contain alcohol instead of mercury. Ray
