Question

The element which exists in liquid state for a wide range of temperature and can be used for measuring high temperature is

A. $$B$$
B. $$Al$$
C. $$Ga$$  
D. $$In$$
Answer :   $$Ga$$
Solution :
Gallium $$(Ga)$$  with unusually low melting point $$\left( {303\,K} \right),$$  can exist in liquid state during summer. Its high boiling point $$\left( {2676\,K} \right)$$  makes it a useful material for measuring high temperature.
