    Give reasons why water is considered unsuitable for use in thermometers.

    Answer:

                    Water is considered unsuitable for use in thermometers due to following reasons: (i) The expansion of water with temperature is non-uniform. (ii) Due to its large specific heat and low thermal conductivity, a water thermometer does not respond to changes in temperature quickly. (iii) Water is invisible, sticks to glass and has high rate of evaporation. (iv) Its temperature range is small from \[0{}^\circ \text{C}\] to \[\text{1}00{}^\circ \text{C}\]
