MCQ
The element which exists in liquid state for a wide range of temperature and can be used for measuring high temperature is :-
- A$B$
- ✓$Ga$
- C$Al$
- D$In$
✓
Answer
Correct option: B.
$Ga$
b
The melting point of gallium is $30^{\circ} \mathrm{C}$ and boiling point is $2240^{\circ} \mathrm{C}$. Thus, the element exists in liquid state for a wide range of temperature.
