Why is mercury in a thermometer instead of colored water?
Because mercury has properties in it that react to temperature, but coloured water would just stay at the same level the whole time.
Would you rather use alcohol or Mercury in a thermometer?
Alcohol. Mercury is very toxic.
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 mercury used in thermometer instead of water?
Mercury is a good conductor of heat and it expands to certain levels when heated to certain temperatures.In addition:Water would freeze when the temperature went below 32 degrees F. or 0 degrees C. See the related link for more information. Mercury has a higher boiling point and hence would not evaporate after 100 degree Celsius, like water, and this enables us to measure temperatures beyond it but if we see that as mercury is an good conductor of heat and it is expand to its level when we heat
What would you measure water temperature with?
A mercury thermometer (but not a medical one!)
Would ethanol be better than mercury for an outdoor thermometer in the arctic?
Ethanol would be better because it has a smaller range.
Why is water not used as a liquid in a thermometer?
because the mixture of ice and water has an equilibrium temperature of 0 C and thus it will be the first calibration system and making sure that thermometer is working properly. The thermometer will have better contact with the water than with lumps of ice and therefore adjust better to its temperature.

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.
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 cant you use a mercury thermometer to measure the melting point of gold?
The thermometer would melt
Would you rather use alcohol or Mercury in a thermometer?
Alcohol. Mercury is very toxic.
What would you measure temperature with?
A Mercury thermometer (but not a medical one!)
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
Would a common mercury thermometer be feasible if glass and mercury expanded at the same rates for changes in temperature?
no
Why would a mercury thermometer not work below -39 degrees Celsius?
A mercury thermometer wouldn't work -39 degrees Celsius because, it would have to be at a certain temperature to get the right calculations and it has to be a certain temperature
