Explain how a liquid thermometer measures temperature?
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.
What is a thermometer bore?
A bore refers to the extremely fine or narrow tube found in a thermometer. It is called a narrow bore or a capillary.
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.
How does a glass stem thermometer measure?
A glass stem thermometer measures temperature through the expansion and contraction of a liquid, typically mercury or colored alcohol, contained in a sealed glass tube. As the temperature increases, the liquid expands and rises in the narrow stem, while it contracts and descends as the temperature decreases. The temperature is read by observing the level of the liquid against a calibrated scale printed on the glass. This method allows for accurate temperature readings based on the physical properties of the liquid used.
Why does the liquid expand in a thermometer when it gets hotter?
The liquid in a thermometer expands when it gets hotter because heat causes the molecules in the liquid to move faster and spread out, leading to an increase in volume. This expansion is what causes the liquid to rise up the tube of the thermometer, indicating a higher temperature.
What happens to the liquid in the thermometer when it gets colder?
When the liquid in a thermometer gets colder, it contracts and decreases in volume. This causes it to move down the tube of the thermometer, indicating a lower temperature.
How does the temperature increase on a thermometer?
Temperature increase on a thermometer is typically indicated by the expansion of the liquid or mercury within the tube. As the temperature rises, the molecules in the liquid move faster, causing it to expand and rise up the scale on the thermometer. This expansion is calibrated to reflect the corresponding increase in temperature.
How does the liquid in a thermometer move up and down?
When the liquid in the thermometer gets warmer it expands. This means its volume increases. The only place for the extra volume to go is up the tube, so the level of liquid rises. When the liquid gets colder it contracts (reduces in volume) so it moves back down the tube. See http://www.energyquest.ca.gov/how_it_works/thermometer.html
Why is liquid used in thermometer?
Liquid is used in a thermometer because it expands and contracts uniformly with changes in temperature, allowing for accurate temperature measurements. The liquid inside the thermometer expands and rises in the capillary tube as it gets warmer, providing a visible indication of temperature.

What is liquid-in-glass thermometer?
A liquid-in-glass thermometer is a type of thermometer that consists of a glass tube filled with a liquid, typically mercury or alcohol, which expands or contracts with changes in temperature. The level of the liquid in the tube corresponds to the temperature, allowing for temperature measurement.
How a liquid thermometer works using thermal expansions?
In the right conditions and circumstances all liquids will expand
Why does a thermometer rise up when its hot?
When a thermometer is exposed to heat, the molecules inside it gain energy and move faster, causing them to spread out. This expansion leads to the fluid inside the thermometer rising up the tube, indicating a higher temperature.
How the liquid in a thermometer change so that it can be used to measure a temperature?
The liquid in a thermometer expands and contracts as the temperature changes. This causes the liquid to rise or fall in a narrow tube connected to the bulb of the thermometer. The markings on the tube indicate the temperature based on how high or low the liquid level is.
How does an air thermometer work?
An air thermometer has a bubble of liquid inside the tube and when the air inside of the tube heats up or cools down, the air takes up either more or less space inside of the tube, causing the bubble of liquid to either move upwards or downwards, indicating the temperature.
What happen to the liquid in a thermometer when it gets warm?
When a thermometer is exposed to warmth, the liquid inside it expands and rises up the tube. This is because heat causes the molecules in the liquid to move faster, taking up more space and causing the volume to increase. The expansion of the liquid is used to measure the temperature.
