Question

Why cannot water be used in thermometer?

Answer 1

Water cannot be used in thermometers, it is because water is transparent so we cannot take the readings properly.
Another reason is that is it too wet that it sticks to the walls of thermometer.
So we prefer mercury in thermometers.
It is easy to take reading and also it doesn't stick to the walls of the thermometer.
Also, water have high boiling point than mercury.
