One way of checking to see if a thermometer is working properly is to get a second one and see if the temperatures match.
Another method thing you can do is put it in your mouth, and it should read around 98.6 degrees Fahrenheit 37 degrees Celsius.
You put a thermometer in it, for at least a minute, and then read the thermometer with the bulb still in the liquid.
A thermometer measures temperature through a glass tube sealed with Mercury that expands or contracts as the temperature rises or falls.
A thermometer will measure the temperature of a liquid.
Such thermometers are based on the fact that the liquid expands when the temperature increases. That's what the thermometers measure.
A thermometer is used to measure air temperature, or the temperature within a solid or liquid.
You can insert a thermometer directly into a liquid, but not into a solid. You can fairly easily measure the surface temperature of a solid object, but that does not necessarily reflect the temperature inside.

You're measuring the boiling point of the liquid.
they both measure temperature
Kelvin and celsius scale
The answer depends on what you want to measure: its mass, length, "equatorial" circumference, volume, density, temperature, conductivity, ...
A thermometer used to measure air temperature uses a glass tube filled with a liquid either alcohol or mercury. When the temperature increases the particles of liquid expand, filling the glass tub. Thermometers that are used to measure you body temperature uses infrared sensors.
Temperature is the measure of thermal energy. And how you measure thermometers is that if the liquid expands when its temperature increases. The height of a column of the liquid inside the tube shows the temperature.
A thermometer measures temperature by using the liquid inside of the thermometer. It measures temperature by Celsius and Fahrenheit.
