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.
What are mercury barometers?
A barometer measures air pressure. A mercury one does so by taking a tube full of mercury which is inverted into a dish of mercury. The height of mercury remaining in the tube is a measure of the air pressure.
Why does a thermometer rise up when its hot?
Usually when a thing gets hot, it expands. The liquid in the thermometer gets hot, and expands, so it takes up more room in the tube.
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

What was the first liquid used in a thermometer?
The first thermometer was a tube filled with water and air.
How a liquid thermometer works using thermal expansions?
In the right conditions and circumstances all liquids will expand
What change takes place in the liquid inside a thermometer when it is placed into somthing cold?
The liquid inside the thermometer "contracts" when it is placed into something cold. This means that it decreases in volume and increases in density. This is the reason that the thermometer can measure heat: the volume of the liquid inside the thermometer changes as a function of heat, and the amount of liquid in the "tube" of the thermometer changes as a function of volume. Because of this relationship, the level of the liquid in the tube of the thermometer changes as a function of heat.
What causes liquid in thermometer to travel up and down in tube?
Heat causes Mercury in the thermometer to expand, where as when it is cooled, it contracts.
Is the external bulb of a thermometer also made of mercury?
The red liquid in a thermometer is Mercury, which is usually encased in a glass tube

What happens when liquid in a thermometer undergoes thermal expansion?
The liquid rises, indicating a temperature.
What is the advantage of having a skinny tube in a thermometer?
The principal of the skinny tube is to allow expanded liquid to pass up it to indicate temperature
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.
