Mercury is commonly used as a thermometric fluid rather than water because
specific heat of mercury is less than water
specific heat of mercury is more than water
mercury has greater visibility than water
density of mercury is more than the water

Liquid Mercury has a very low vapor pressure than water. So it will be more sensitive than water to the changes in the atmospheric pressure and ups faster to store the changes.

I think option A is correct because mercury can detect small change in temperature but water can't. Only the visibility can't be the reason for the use of mercury.

One can use color in water if it is about visibility only, at least provide suitable and more scientific information rather than being layman.

Both specific heat capacity and the density of mercury has higher and lower simultaneously that's why both options are correct.

Clement said:   1 decade ago
Mercury is preferred because it is very sensitive to very small change in temperature due to its high density.

I have a question. Why does mercury appear to defy the law of gravity when subjected to the extreme cold?

Syed Azhar said:   10 years ago
It is very confusing because someone's comments are A option and other one is C.

Which one is right?

Garang John said:   9 years ago
My option is also "C" because of it great visibility whereby mercury can also show the less like 11.

Centrik said:   9 years ago
C is the correct answer.

Mercury can be seen compared to water. Because of its silvery colour.

Can WATER be really used in a thermometer? I thought it was alcohol only.
