Does mercury stay in the tube or escape into the air?
Mercury stays contained in the tube of a mercury thermometer when in use. It does not escape into the air as long as the thermometer is intact. However, if the thermometer is broken or improperly disposed of, mercury vapor can be released into the air, which is harmful to health.
How does a liquid-filled thermometer measure temperature accurately?
A liquid-filled thermometer measures temperature accurately by using the principle that liquids expand or contract with changes in temperature. As the temperature increases, the liquid inside the thermometer expands and rises up the tube, providing a visual indication of the temperature. Conversely, as the temperature decreases, the liquid contracts and moves down the tube. The markings on the thermometer scale correspond to specific temperature values, allowing for accurate measurement.
How do you fix a thermometer where the mercury is separated in the tube?
You can't and shouldn't repair this. Mercury being poisonous, it is best recommended to discard the whole thermometer, without letting the mercury escape, very carefully. Maybe where you live they have a special place where such objects are destroyed safely.
Why the mercury can not rise in a lab thermometer if there is air in the glass tube?
Mercury does not rise in a lab thermometer if there is air in the glass tube because the presence of air creates pressure within the tube that opposes the expansion of the mercury. Without a vacuum, the air pressure prevents the mercury from moving freely up the tube in response to changes in temperature.
What color tube is used for Platelet function studies?
Platelet function studies are typically collected in a blue-top tube (sodium citrate) to prevent clotting and maintain the function of platelets for analysis.
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.
The function of a Mercury thermometer?
A Mercury thermometer measures temperature by relying on the expansion and contraction of the liquid mercury inside the glass tube. As the temperature changes, the mercury expands or contracts, causing it to rise or fall in the tube, indicating the temperature.
What is the function of the bore in a thermometer?
The bore in a thermometer is the narrow tube where the liquid (mercury or alcohol) expands and contracts with temperature changes. This expansion and contraction of the liquid in the bore allows the thermometer to measure and display the temperature accurately.
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.
Function of cork borer?
Very simple answer: to make a hole in a cork or plastic stopper; the scope is to insert a tube, thermocouple, thermometer, etc.
Who element used of the glass tube of clinical thermometer to measure thermometer?
mercury
What is a capillary tube in instrumentation terms?
a thermometer--
Why is the thermometer placed in a tube separate from the culture?
If the thermometer was in a culture tube it would interfere with the subsequent transfers of culture to plates across the time intervals.
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 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.
What is functions of bent tube at distillation?

What is inside the glass tube from a thermometer?
either mercury or alcohol
