What makes mercury in a thermometer go up and down?
Change in temperature is what cause the Mercury to expand up (hotter) or shrink down (colder).
Why do you use mercury in thermometer?
As tempertature rises, the mercury in the thermometer expands, causing it to go up. As temperature decreases, the mercury in the thermometer contracts, causing it to go down on the scale. However, mercury thermometers are very dangerous if it breakes and gets on your skin. so it it reccomended to use an electric thermometer. these thermometers use thermoelectric current to measure temperature. ergo. they are safe if they break cheers <3 -Eli
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.
You are planning to go to a very cold place where the night temperature drops to minus 50 deg c which thermometer will you take with you- mercury or alcohol and why?
I would take an alcohol thermometer because it can accurately measure temperatures as low as -70 degrees Celsius, whereas a mercury thermometer may not work reliably at such low temperatures. Additionally, alcohol is less likely to freeze at extremely cold temperatures compared to mercury.
How high does a thermometer go?
107 degrees Fahrenheit, because once a human reaches that temperature they're basically cooked from the inside. It's kinda like a hard-boiled egg.
Why can a mercury thermometer be used only at high temperatures?
A mercury thermometer can go down to -30 deg C

What makes mercury go up and down a thermometer?
the heat and temperature that causes it to rise and fall.
Can a meat thermometer go in the oven for accurate temperature readings?
Yes, a meat thermometer can go in the oven for accurate temperature readings as long as it is an oven-safe thermometer designed for high heat cooking.
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.

Why does mercury level goes down for a very short time when a mercury-in glass thermometer is placed in hot water?
The exterior of the bulb of the thermometer expands first, resulting in the mercury level to go down. After that the mercury in the bulb expands more than the glass bulb, resulting in the subsequent rise of the mercury level.
Why does temperature in a thermometer go up faster when shaken?
When a thermometer is shaken, the mercury inside it gains kinetic energy, causing its particles to move faster and spread out more. This makes the mercury rise in temperature more quickly as it absorbs heat energy from the surroundings.
Which thermometr will you take when you go to south expedition mercury or alchol?
An Alcohol thermometer would be the best as it is more sensitive than the mercury thermometer.
Why do thermometer contain Mercury?
Mercury is a liquid at room temperature. When it heats up it expands, and when it cools it contracts. This is the re line that you see, and shows the temperature accurately. You usually have mercury because it is a liquid at room temperature, so it can go up and down freely. Hope this helps :)
