The cold reduces the temperature in the liquid inside the thermometer bulb. Most substances contract when their temperature drops so the liquid in the bulb occupies less space. this causes the column of liquid outside the bulb to become smaller.
This depends on the thermometer model.
The liquid in a thermometer does not move when turned upside down because of the properties of the liquid used (usually mercury or alcohol) and the vacuum-sealed tube design of the thermometer. This design prevents the liquid from freely moving when the thermometer is inverted.
We still use colored alcohol for our liquid in everyday thermometers.
When the liquid in a thermometer contracts, it means that the temperature is decreasing. As the molecules of the liquid lose energy, they move closer together, causing the volume of the liquid to decrease. This contraction is used to measure a drop in temperature on the thermometer scale.
Within the thermometer's range of operation, a given temperature difference will result in the same expansion in the column of the thermometric liquid.
When a thermometer is heated, the liquid particles gain energy and move faster, causing them to spread out and rise in the thermometer's tube. This expansion of the liquid column indicates an increase in temperature on the thermometer scale.
The two substances used in a liquid column thermometer are mercury and alcohol. Mercury thermometers use mercury as the liquid inside the glass tube, while alcohol thermometers use colored alcohol such as ethanol or dyed ethanol.
The constriction in a clinical thermometer allows for expansion and contraction of the liquid inside without separating the column of liquid. This ensures accurate temperature readings by preventing the liquid from breaking and forming air bubbles.
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.
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.
The cold reduces the temperature in the liquid inside the thermometer bulb. Most substances contract when their temperature drops so the liquid in the bulb occupies less space. this causes the column of liquid outside the bulb to become smaller.
When the temperature increases, the mercury in a thermometer expands and rises up the column because the volume of the liquid increases with temperature. This expansion is linear and is used to indicate the rise in temperature on the thermometer scale.

A lab thermometer typically has a narrower temperature range and higher precision compared to a liquid thermometer. It may also be designed specifically for use in laboratory settings with features like resistance to chemicals or breakage resistance. Liquid thermometers use a column of liquid, such as mercury or alcohol, to measure temperature, while lab thermometers may use different mechanisms like resistance temperature detectors or thermocouples.
Mercury the liquid inside thermometer is mercury.. but it is called thermometric liquid.
When the liquid in the thermometer gets warmer it expands.
