When the glass thermometer is in contact with a warmer object, conduction will cause the galss bulb to warm. This will cause the liquid inside the bulb to warm and, as a result, to expand. Since this liquid has nowhere else to go, it will expand into the capillary at the end of the bulb. The capillary is placed next to a graduate scale which is calibrated to give the temperature.
This is possible becaue exit a linear relation between the temperature and the dilatation of a liquid.
Thermometers with liquid contain Mercury, colored ethanol, melted gallium, etc.
No power source is required, repeatable and calibration doesn't drift.
gas thermometer are more sensitive then liquid thermometer
what do they use for the liquid in glass ball thermometer
A so-called "glass" thermometer has a small bore-hole in the center of the glass that has some liquid in it. It's the activity of the liquid in the narrow hole that makes the thermometer a thermometer.
thermometer
As the liquid in the thermometer is heated it expands, and the only way the expanding liquid can go is upward. As the liquid in the thermometer cools, it will contract, and the liquid will fall back down into the resevoir, causing the column of liquid to move downward.
a liquid thermometer is made with a glass "shell" and ussually have murcur inside them that dilates when it gets hotter and rises and contracts when its colder and lowers- this has been made by a 12 year old boy

For a classic thermometer: glass and mercury, colored ethanol or another liquid.

A laboratory thermometer is used to check the temperature, or changes in temperature, of an object with precise accuracy.
Yes, above the mercury or the other liquid.
