OK basically depending on what thermometer. the glass tube is filled with either alcohol or Mercury. and when it gets hotter, the liquid expands and takes up more space inside the tube. and colder.......the liquid compacts and moves down the tube.....and it's taken years to calabrate the markings on the tube to show the correct reading.
When the liquid in a thermometer is warmed, the liquid (mercury) rises higher and tells us that the temperature is rising, therefore, when the liquid is cold, it will lower. Also, the reason why the liquid can lower and rise is because of the humidity and air pressure.
As the applied temperature increases, it expands in the glass tube of the thermometer. This expansion is correlated to the graduations, which we read directly.

Another effect, not relevant to the function of the thermometer, is that when the liquid expands, there is a corresponding decrease in its density.
A liquid thermometer has a sealed capsule in the shape of a long narrow tube attached to a large bulb. The bulb acts as a reservoir for the liquid. An increase in temperature causes a thermal expansion of the liquid. This pushes the liquid higher up into the narrow tube. The tube is mounted alongside a calibrated scale which allows the user to read off the temperature.
The principle is based on the fact that dilatation of the thermometric liquid is proportional to temperature.

What features do a lab thermometer and a liquid thermometer have in common?
they both measure temperature
How does a thermomerator measure temperature?
that depends on what type of thermometer. The tube thermometer, the kind with a glass tube with a red liquid in it, uses a small amount of mercury in a very small tube. When the mercury is heated, it expands, pushing further up the tube, as it cools it contracts, going down the tube. A dial thermometer also works on expansion and contraction, but with a coil instead of mercury.
What is a thin glass tube with a bulb on one end that usually contains a liquid usually mercury or colored alcohol?
This could describe a thermometer. The only thing missing is the graduations. That way the height of the column can be associated with a specific temperature, the one that caused the column to be as high as it is.
What liquid metal is most commonly used in thermometer?
The liquid metal in many thermometer is mercury (Hg).
Jill used this thermometer to measure the temperature of a liquid she reports her results as 72 degrees is this a good description?

What does a thermometer measure and how does it do it?
A thermometer measures temperature by detecting changes in the volume of a liquid (usually mercury or alcohol) or a digital sensor in response to temperature changes. It works on the principle that substances expand when heated and contract when cooled, allowing the thermometer to display the temperature accordingly.
Ho does a thermometer measure temperature?
A thermometer measures temperature by using a substance that expands or contracts with temperature changes, such as mercury or alcohol. As the substance heats up or cools down, it moves along a scale marked on the thermometer, providing a reading of the temperature.
What measures the temperature of the liquid?
A thermometer is most commonly used to measure the temperature of a liquid. Other methods, such as infrared thermometers or thermocouples, can also be used depending on the specific application and characteristics of the liquid.
What is the the name of the object a thin glass tubbed filled with liquid that measures temperature?
Thermometer
An object which measures temperature?
A thermometer is an instrument used to measure temperature. It typically consists of a bulb containing a liquid (such as mercury or alcohol) that expands and contracts with temperature changes, which is then converted into a numerical temperature reading on a calibrated scale.
What does an analog thermometer measure?
An analog thermometer measures temperature by using a liquid (like mercury or alcohol) that expands or contracts with changes in temperature, which causes the level to rise or fall in a narrow tube to display the temperature.
How does the instrument used to measure air temperature differ from the instrument used to take your temperature?
Those thermometers use liquid crystals to measure temperature. More specifically, they use chiral nematic liquid crystals--long asymmetric molecules that arrange themselves in orderly spirals in the liquid. When light strikes these spiral structures, some of it reflects. But the reflection is strongest when the light's wavelength is an integer or half integer multiple of the spiral's pitch--the distance between adjacent turns of the spiral. Since light's wavelength is related to its color, the light reflected by these liquid crystals is colored. Because the pitch of a chiral nematic liquid crystal changes with temperature, so does its color. Slightly different liquid crystals are inserted behind each number on the thermometer so that each number becomes colored at a different temperature. copied from: http://rabi.phys.Virginia.edu/HTW/thermometers_and_thermostats.html
How does a glass stem thermometer measure temperature?
A glass stem thermometer measures temperature by using the principle of thermal expansion. The liquid inside the glass stem expands or contracts with temperature changes, causing the level of the liquid to move up or down the scale. This movement indicates the temperature.
How does a mercury thermometer measures temperature?
A mercury thermometer measures temperature based on the expansion or contraction of the liquid mercury inside the narrow tube. As temperature rises, the mercury expands and travels up the tube, indicating a higher temperature, and vice versa. The temperature reading is taken at the point where the mercury level stabilizes.
The function of a Mercury thermometer?
A Mercury thermometer measures temperature by relying on the expansion and contraction of the liquid mercury inside the glass tube. As the temperature changes, the mercury expands or contracts, causing it to rise or fall in the tube, indicating the temperature.
Does thermometer measure heat or temperature?
A thermometer measures temperature, not heat. Heat is a form of energy, while temperature measures the intensity of that energy. Thermometers detect the average kinetic energy of particles in a substance.
Why does the thermometer go down when the temp gets cold?
A thermometer measures temperature based on the expansion or contraction of the liquid or metal inside it. When it gets cold, the molecules inside the thermometer contract, causing the liquid or metal to shrink, which in turn results in the reading on the thermometer going down.
