Why is the bulb of a thermometer the most important part of a liquid thermometer?
you can use two main liquid substances in a bulb of a thermometer - the one i can remember -alchol-another one i am almost certain of -mercury- i am sorry if the later one is incorrect -if you do know the awnser i would appecheate if you conferm it for me .Remember you do not need to be a member or do anything to write an awnser .
Is the external bulb of a thermometer also made of mercury?
No, the external bulb of a thermometer is typically made of glass to hold the mercury inside. Mercury is usually contained within the glass bulb to measure temperature accurately without exposing the user to the toxic substance.
How do you take the reading of a thermometer?
After the thermometer has come into thermal equilibrium with the object being measured, the top level of the liquid (mercury or alcohol thermometer) is the temperature. The indicators will often also be colored red on mechanical (coil expansion) thermometers. Digital thermometers should be "locked" at the recorded temperature if the probe is to be removed before viewing, as it may heat or cool even during a very short interval.
How do you know if its mercury or alcohol your thermometer broke in and around the pool Help?
Mercury is a metal so it will sink to the bottom of the pool where an alcohol will float. Actually, it's more likely that alcohol will simply disperse into the pool; low molecular weight alcohols are extremely soluble. A simpler way to tell is the color: mercury is silver and looks, well, metallic; alcohol in thermometers is generally colored either red or blue simply to make it easier to see. (A lot of people think mercury is red, but it isn't. Some mercury COMPOUNDS such as cinnabar are red, but those are not used in thermometers.) The fact that the liquid in the thermometer is metallic does not necessarily mean that it is mercury; it might be a gallium alloy. However, since mercury is toxic, if you're not sure it's probably safer to assume that it was mercury and treat the spill accordingly.
What is a soft orange-red mineral?
Realgar is an orange-red mineral used in pyrotechnics and as a pigment for tanning.
What do you call the thermometers with the red stuff in it?
Mercury is a silver-white to dim substance. In the event that your thermometer is loaded up with a red fluid, your thermometer contains red colored liquor or mineral spirits and not mercury.
What is the name of the liquid in a thermometer?
The red liquid in a liquid-in-glass thermometer is mineral spirits or ethanol alcohol mixed with red dye. A grey or silver liquid inside the thermometer is mercury. Mercury thermometers are not used anymore due to the dangers associated with mercury.
Why does a red thermometer smell?
A red liquid inside a thermometer, often colored with mercury or alcohol, can emit a metallic smell when exposed to air as these substances are volatile. The smell is more noticeable when the thermometer is broken or if the liquid is spilled, releasing the odor into the air.
What does it mean if the red dye is separated in a thermometer?
If the red dye in a thermometer is separated, it likely means that the thermometer has been exposed to extreme temperatures or has been mishandled, causing the dye to separate from the liquid inside. This can affect the accuracy of the thermometer readings and may require replacing the thermometer.
How do you rejoin red liguid in a thermometer?
To rejoin the red liquid in a thermometer, gently tap the thermometer against a hard surface to encourage the liquid to move back down into the bulb. Alternatively, you can hold the thermometer upright and give it a few firm shakes. Avoid using excessive force, as this could break the thermometer. Always ensure safety precautions when handling glass thermometers.
What is the significance of the red spirit in a thermometer?
The red spirit in a thermometer is typically made of alcohol or a similar liquid that expands and contracts with temperature changes. This allows the thermometer to accurately measure and display the temperature. The red color makes it easier to see and read the temperature level.
What is in the laboratory thermometer?
There are many kinds of thermometer in use. Liquid in glass thermometers usually contain alcohol (dyed red or blue) or mercury (silvery coloured).
What is red substance in thermometer?
The red substance in a thermometer is typically mercury. Mercury is used in thermometers because it expands and contracts uniformly with changes in temperature, making it an effective liquid for measuring temperature accurately.
What is the red stuff in a thermometer?
The red liquid in a thermometer is typically mercury. Mercury is used because it expands and contracts uniformly with changes in temperature, allowing for accurate temperature readings. However, due to the toxicity of mercury, many modern thermometers use safer alternatives like alcohol or digital sensors.
Why does the Mercury in a thermometer appear red?
The red appearance of the mercury in a thermometer is due to the use of red dye in the mercury to make it more visible against the clear glass tube. The dye helps in magnifying small changes in temperature by making the level of mercury easier to read.

What does a thermometer contain water or Mercury?
If it's a silver liquid it's mercury, if it's red it's alcohol (not water)
