Because Mercury expands in heat, it is more accurate than other elements used in thermometers.
The sensitivity of a thermometer refers to the minor temperature transform that can be detected or considered. The sensitivity of a thermometer is defined as the increase in the length of the Mercury column per unit increase in temperature. The range of a thermometer, on the other hand, refers to the dissimilarity between the maximum and the minimum temperature. It is calculated in meter/degree Celsius.
Glass is used for the stem of a thermometer because it is transparent, chemically inert, and has a low thermal conductivity. These properties allow for accurate readings of temperature as the glass does not interfere with the temperature being measured.
The glass around the bulb in a clinical thermometer (the conventional one) is thin because glass is not a good conductor of heat. The clinician and the patient don't want to wait half an hour to get a good temperature reading. By using the thinner glass, the transfer of heat into the thermometer's fluid will be more rapid than it would with an instrument with thicker glass.
the thermometer is thin because it is faster to read the temperature
Most likely because glass is both cheap and a pretty good thermal conductor.
Probably because it is transparent, and durable, and doesn't have much thermal expansion.

Which thermometer is a greater health hazard if it breaks Is it the mercury in glass or alcohol in glass thermometer?
Mercury in glass thermometers pose a greater health hazard if broken, as mercury is a toxic substance that can be harmful if inhaled or ingested. Alcohol in glass thermometers are considered less hazardous as alcohol is not as toxic as mercury. It is still important to clean up any broken thermometer carefully to avoid injury.
How are thermometer made?
Thermometers are typically made by placing a temperature-sensitive material, like mercury or alcohol, inside a sealed glass tube. As temperature changes, the material expands or contracts, causing it to move up or down the tube to indicate the temperature. The tube is then calibrated with temperature markings to indicate accurate readings.
Why are the properties of Aluminum always the same while the properties of the lead - glass may vary?
The properties of aluminum are consistent because aluminum is a pure element with a uniform atomic structure. Lead-glass, on the other hand, is a composite material made up of lead and glass, which can vary in composition and texture, leading to different properties. The variations in lead-glass properties stem from differences in the ratios of lead to glass and the manufacturing process.
Which part of the CNS is made up of the midbrain pons and medulla and oblongata?
The brain stem.
What is the importance of thermometric liquids?
Thermometric liquid is the liquid found in the thermometer that help in the up and down movement of the temperature.
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.
Why is the stem of thermometer made up of glass?
Glass is chosen for thermometer stems because it is transparent, allowing easy observation of the liquid inside. Glass is also chemically inert, resistant to thermal expansion, and can be easily calibrated for accurate temperature readings. Additionally, glass is non-reactive with most substances, ensuring that measurements are not affected by the material of the stem itself.
Why a mercruy in a glass thermometer holes up a uniform stem?
because it is cheap and it does not expand on heating therfore it doesnt break
Why does the substance in the thermometer stem rise up?
The substance in the thermometer stem rises up because it expands when heated. This expansion is due to the particles within the substance moving more rapidly and spreading further apart, causing the substance to take up more volume and rise up the stem of the thermometer.
Explain how an ordinary glass fever thermometer is designed?
An ordinary glass fever thermometer is typically made of a sealed glass tube filled with mercury or dyed alcohol. It has a calibrated scale along the length of the tube to measure temperature. When the thermometer is placed in contact with a warm object, the temperature causes the liquid inside to expand and rise up the scale, indicating the temperature value.
What should you not do while using a glass thermometer?
shove it up ur ASSS
What is thermometer made up of?
A thermometer is typically made up of a glass tube filled with a liquid such as mercury or alcohol. The liquid expands and rises in the tube as the temperature increases, allowing the user to read the temperature from the scale on the side of the thermometer.
Why are the thermometers called liquid in glass thermometers?
Liquid-in-glass thermometers are called so because they contain a liquid (usually mercury or alcohol) enclosed in a glass tube. When the temperature changes, the liquid expands or contracts, moving up or down the tube to indicate the temperature.
Which thermometer is a greater health hazard if it breaks Is it the mercury in glass or alcohol in glass thermometer?
Mercury in glass thermometers pose a greater health hazard if broken, as mercury is a toxic substance that can be harmful if inhaled or ingested. Alcohol in glass thermometers are considered less hazardous as alcohol is not as toxic as mercury. It is still important to clean up any broken thermometer carefully to avoid injury.
Who invented the water thermometer?
Charles WingerThe Thermometer was invented by Galileo Galilei in 1593. His thermometer consisted of water in a glass bulb; the water moved up and down the bulb as the temperature changed.
What is a fiber made up made up of?
It's made of glass.
What makes a liquid in glass thermometer sensitive to a small changes in temperature?
As the temperature rises or falls the liquid in the reservoir (bulb) of the thermometer rises or falls ) the liquid expands (heats up) or contacts (cools off). The volume change is made visible in the capillary (tube) in the part of the thermometer with the scale. This is the only part of the thermometer into which the extra volume and expand.Increasing the volume of fluid or decreasing the diameter of the capillary makes the changes more apparent/
