Solution- Low melting point: Gallium has a melting point of 29.76 degrees Celsius which is relatively low compared to other metals. This property allows gallium to melt easily at body temperature, making it suitable for use in medical thermometers.

High boiling point: Gallium has a boiling point of 2403 degrees Celsius.This high boiling point ensures that gallium remains in a liquid state at elevated temperatures, making it suitable for measuring high temperatures.
