Why is an alcohol thermometer better than mercury in the freezer?

Dropped Mercury thermometers account for almost half of the spills that occur each year on campus. Rarely do people have the mercury spill kit required to clean up the half a gram of mercury that can escape from these thermometers. If someone drops a mercury thermometer in your lab, you lose time, money, and possibly your clothing or equipment. Instead, recycle your mercury-filled thermometers through EH&S and we'll deliver a free alcohol-filled thermometer in exchange. Our alcohol thermometers are semi-submersible and measure from -20 to 110ºC to within 1º. They perform most routine laboratory functions that mercury thermometers are used for, such as measuring the temperature of water baths or ambient air. And best of all, when you drop one, all you have to do is wipe up the liquid with a paper towel and throw it away, and place the broken glass in your lab glass bin.

∙ 9y agoA home freezer's ideal temperature for storing food is approximately -18 degrees Celsius. Mercury freezes at about -39 degrees Celsius, which is fairly close to the desired freezer temperature and can thus damage the thermometer. Ethanol, a common alcohol used in alcohol thermometers, freezes at -114 degrees Celsius, allowing it to properly function in freezers.

∙ 16y agomercury doesn't freeze till about -30F, so it should work ok for normal freezer temperatures of 0F

∙ 14y agoAlcohol based thermometers must be used in very low temperatures because alcohols may have a freezing point as low as -114 °C, while mercury has a freezing point of -38.83 °C.

Would it be better to cool a soda faster in the freezer or fridge?
The Freezer.
Is a frost free freezer better than a normal freezer?
Frost-free freezers will keep down the moisture produced by your refrigerator. They also enable a larger amount of space in the freezer compartment by preventing moisture to encompass the areas around your freezer.
Would glass or plastic shelving be better in a freezer and can you explain your choice?
Plastic shelving would be better in a freezer than glass because the extreme cold would make the glass more brittle and thus more likely to break.
Where would the doctor place the clinical thermometer to take your body temperature?
use a thermometer (ear, digital, rectall or pacifier) and put the digital underneath your tongue and wait till it beeps. the same with the rest but the ear thermometer in the ear and rectall thermometer in the rectall. Hope you get better soon xox <3
Which is more better to use a glass thermometer or a plastic thermometer?
There is no difference in the effectiveness of glass or plastic. Glass is more fragile for breaking but easier to keep clean, plastic is safer for not breaking, and harder to keep clean longer. It is a personal choice.
What does cimecels mean?
Cimecels has something to do with Mercury being better then Alcohol on a thermometer.
Are alcohol thermometers better than mercury thermometers?
Both alcohol and mercury thermometers are effective for measuring temperature, but alcohol thermometers are generally safer to use due to the toxicity of mercury. However, mercury thermometers provide more accurate readings at higher temperatures compared to alcohol thermometers.
Would ethanol be better than mercury for an outdoor thermometer in the arctic?
Ethanol would be better than mercury for an outdoor thermometer in the Arctic because ethanol has a lower freezing point than mercury, making it more reliable in extremely cold temperatures. Additionally, ethanol is less toxic than mercury, which is important for environmental and safety reasons in outdoor settings.
Compare the expansion of mercury with alcohol?
Mercury expands less with temperature changes compared to alcohol, which has a higher coefficient of thermal expansion. This means that alcohol is more sensitive to temperature changes and exhibits greater expansion and contraction when heated or cooled.
Which is better mercury or alcohol thermometers for low temperature measurements?
Alcohol thermometers are generally better for low temperature measurements as they have a wider temperature range, reaching lower temperatures than mercury thermometers. Additionally, alcohol is less toxic than mercury, making it safer to use in certain applications.
Can frozen alcohol catch on fire?
No, frozen alcohol cannot catch on fire because the alcohol must be in a gaseous state to ignite. Frozen alcohol is solid and does not produce flammable vapors that can ignite.
Why mercury is use instead of water in a thermometer?
when measure a very hot body with water inside the thermometer, the glass will break or the water will evaporate, similarly if we measure a cold body with the water again the water inside will freeze and we wont know thew correct measure
Why clinical thermometer is jerked before using it again?
If you have an old thermometer that has mercury, then the shaking makes all of the mercury flow to the bottom of the thermometer. Then, you can get a better reading. The current digital ones work differently. Thermometers used for taking people temperatures are a special kind that go up with heat but don't go down with cold. So you have to shake a thermometer before taking your temperature to make the reading go down below your own temperature. Then the thermometer can go up again to read your temperature.
What dangerous liquid used in thermometers?
Mercury would be the dangerous liquid used in thermometers. Many modern thermometers are made without mercury for safety reasons, but if a thermometer breaks and you're not sure, it's better to be careful with the cleanup.

I don't know about you, but I feel worse in the freezer!
