Solution
A thermometer liquid must expand/contract significantly with temperature change (high thermal expansion coefficient) to show clear readings. It should also require little heat to change temperature (low specific heat) to respond quickly and not affect the system being measured.
Therefore, the correct properties are: Small value of specific heat & large value of coefficient of the thermal expansion.
