Hey
Here is your answer :-
Mercury is used in thermometer because-
1) It's response to heat is faster than any other metal.
2) It is the only metal present in liquid state.
3) Easy to record because of thick and shiny metal.
4) Non sticky to the glass wall so capillary always remains clean.
Hope it helps ✌✌
