Like most materials, Mercury expands when heated.
By storing the mercury in a narrow tube, as the mercury gets warmer (and therefore expands) it will rise up the tube, allowing the temperature to be determined based on how high up the tube the mercury has risen.

What is the working and construction of thermometer?
WORKING: Place the bulb of the thermometer filled with mercury in a vessel ov small pieces of ice the mercury will arise in the tube and will come to rest at a certain point.this point shows the melting point of ice. CONSTRUCTION:A thermometer consists of a glass bulb filled with mercury.A cappilary tube arises from this bulb.Due to the narrow bore of the tube a small change in the volume of the mercury becomes significiantly visible.
Mercury thermometer analog or digital device?
The traditional mercury thermometer has the mercury in a narrow glass tube with the readings/markings etched into the glass so it is neither analogue nor digital. I thought it was analogue.
What is the signal conditioner of mercury-in-glass thermometer?
The capillary tube of the thermometer ( in case of a mecury thermometer).
What happens to the mercury in the thermometer when the air is cool?
In a mercury thermometer, the level of mercury falls as the temperature of the air around it cools.A mercury thermometer has a bulb of mercury at the bottom and a thin tube above it with markings in Celsius degrees or Fahrenheit degrees. When the temperature warms, the mercury expands and rises up the tube. When the temperature cools, the mercury contracts and shrinks back toward the bulb at the bottom.
What is the function of thermometer mercury?
The Mercury expands with temperature. Since expansion is linear over the normal range of a mercury-driven thermometer, the level of mercury within a little glass tube indicates the current temperature of the thermometer's immediate environment.
How mercury rises in thermometer by rising temp?
The mercury in the thermometer's tube expands and contracts due to the surrounding temperature. As the mercury is inside a narrow tube, it can only expand upwards, and contract downwards.

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.
Why does mercury go up or down in a thermometer?
The mercury in the bulb at the bottom of the thermometer expands or contracts depending on the amount of heat (the temperature). The narrow calibrated tube that you read the temperature on acts to amplify this effect. The calibration is usually either in Fahrenheit or Celsius.
What are the constrictions in a thermometer?
The constriction in a thermometer is a narrow region in the capillary tube where the liquid (like mercury or alcohol) is forced to flow through. This helps to amplify the rise or fall in temperature, making it easier to read.
Who element used of the glass tube of clinical thermometer to measure thermometer?
mercury
What is the signal conditioner of mercury-in-glass thermometer?
The capillary tube of the thermometer ( in case of a mecury thermometer).
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
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 inside the glass tube from a thermometer?
either mercury or alcohol
What is in a thermometer besides Mercury?
There is nothing else in a mercury thermometer. However, some similar (glass tube-type) thermometers contain alcohol instead of mercury. Ray
