Water is not considered suitable for use in thermometers. Give the reason for the same.

Explanation

Water is unsuitable for use in thermometers due to the following reasons : (i) The water has anamolous expansion, i.e., the expansion of water with temperature is non-uniform (ii) The temperature range for melting point `0^@C)` and boling point `(100^@C)` is small. (iii) A water thermometer does not respond quickly to changes in temperature as water has high value of specific heat and low value of thermal conductivity. (iv) Water sticks to the glass. It is invisible and has high rate of evaporation.
