If a thermometer breaks and the mercury goes in your pool is it dangerous?
Modern thermometers don't use mercury, they use a colored alcohol solution... and yes it would be dangerous.
Would a common mercury thermometer be feasible if glass and mercury expanded at the same rates for changes in temperature?
no
What is an example of thermal expansion that you have observed in your daily life?
an example would be a thermometer. A thermometer because it has mercury in it. When you check a patients temperature with a thermometer ,the heat from the patients body will cause the expansion of the mercury and the mercury flows in the tube. It stops at a point and that point indicates the temperature in the patients body.
Why is there a constriction in a clinical thermometer?
The constriction prevents the mercury from returning back to the bulb when the thermometer is removed from a particular body.
Why does a clinical thermometer not start at 0 degrees celsius?
For sensitivity, a thermometer should only display the range that is required. Starting at around 35C up to 45C covers the whole range of temperatures that people might record. If the range had to be 0C - 100C, it would make it very hard to read the temperature accurately. Clinical thermometers use alcohol while lab thermometers use mercury,while alcohol has a freezing point of -112 o c mercury has freezing point of -39 o c
Why would you use alcohol thermometer rather then a mercury thermometer in the north pole?
because it would turn to ice and alcohol wouldn't
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.
Does a Kelvin thermometer contain mercury or alcohol?
There is no mechanical difference between a kelvin thermometer and any other kind so I think it would be the same as other thermometers i.e. Alcohol (because it is not as dangerous as mercury)
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.
Why wouldn't you take a mercury in glass thermometer with you to south pole?
If I only had those 2 choices... I would use ALCOHOL since Mercury freezes at -38.72° Celsius. The North Pole can get down below -50° Celsius. Ethanol (alcohol) freezes at -114 ° Celsius Methanol (alcohol) freezes at -97.8° Celsius

Where would you find the element mercury?
It's the red thing in thermometers. [wrong I'm sorry.] the red thread in a thermometer is coloured alcohol. If the thread is mercury, then it will be silver-coloured.
Why not mercury thermometer is used to measure temperature of hot milk?
It could be used to do this - it is capable of doing it. However, Mercury is poisonous and a mercury thermometer is made out of fragile glass. Thus the danger that the thermometer would break releasing mercury into the milk (which would be for a person to drink) means that a mercury thermomiter is not the temperature sensor to use in this instance.
Why cant you use a mercury thermometer to measure the melting point of gold?
The thermometer would melt
What would you measure temperature with?
A Mercury thermometer (but not a medical one!)
What would you measure water temperature with?
A mercury thermometer (but not a medical one!)
Would a common mercury thermometer be feasible if glass and mercury expanded at the same rates for changes in temperature?
no
