Are alcohol thermometers better than mercury thermometers?
They both have advantages and disadvantages: A mercury-in-glass thermometer can measure high temperature (up to 357 0C, the boiling point of mercury; and its freezing point is -39 0C). An alcohol-in-glass thermometer can measure low temperature (down to -115 0C, the freezing point of alcohol; and its boiling point is 78 0C.) A mercury-in-glass thermometer can quickly response to temperature, while an alcohol-in-glass thermometer can only slowly response to temperature. However, mercury is poisonous and alcohol is NOT poisonous. Also mercury thermometers are not allowed on aircraft.
What is the treatment for one who swallowed mercury from thermometer years ago?
If you didn't get treated years ago, then you were fine and are fine, the mercy won't effect you now if it didn't infect you then. It is something else.
When the temperature increases the level of mercury in the thermometre rises why does this occur?
When the temperature rises the mercury ions have more energy. That means they move around faster. Because they are moving faster they are further apart from each other on average, therefore the metal expands in volume. Because of the shape of the inside of a thermometer the mercury can only rise upwards even though it expands in all directions.
What happens to a laboratory thermometer if it measures more than 110 degrees?
I am not sure what sort of thermometers you have in your klab but a mercury-in-glass thermometer should be fine up to 350 deg C. Thermometers based on thermocouples can go very much higher. So the simple answer is that nothing happens.
How can check refrigerator if its working fine?
Unless your refrigerator has a built-in thermometer, you would need to check it with a thermometer. Purchase of a refrigerator thermometer is highly recommended.

How do you tell how hot or cold something is?
use a thermometer.We can feel how hot or cold something is. However, sometimes things are just too hot or cold for us to feel safely. At other times we need to know exactly how hot or cold something is. When we need to measure temperature correctly we need to use an instrument called a thermometer. This measures temperature in degrees Celsius [sometimes called centigrade] or degrees Fahrenheit. There are different types of thermometers for different situations. A medical thermometer, for example, needs to be very accurate. It measures in fractions of degrees. When we are ill, even tiny changes in temperature are important. Some thermometers use a liquid that moves up a very fine glass tube. Most room thermometers, and outdoor thermometers are like this. The liquid is either mercury [ which is poisonous] or coloured alcohol. As liquids get warmer they expand [get bigger], and move up the tube. Water expands too, but not as much as alcohol and mercury. Thermometers that might be used by small children are not made of glass. They use a digital display which lights up the temperature. Inside the displays are chemicals that change colour according to the temperature.
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 the symbol of the planet Mercury?
Hg is the symbol. It stands for hydrargyrum which means water silver. It actually means "liquid silver" but anything close is fine to use.
What are the answers to the impossible quiz book chapter 3?
The answer to this question is "Fine", the only one of the options written the right way up, which makes sense since if you read the question upside-down, "Fine" is the only option that looks upside-down from that perspective.
How is element mercury purified or extracted?
Mercury is extracted from cinnabar by heating and collecting the vapors. In factories, the rock is ground up into a fine powder which is then heated.
What octane rating is suitable for a 1996 Mercury villager?
Regular fuel (87) is fine.
