Question

Name two metals that possess a low melting point.

Answer 1

Melting point: The melting point is the temperature at which a substance changes from a solid to a liquid state.

The melting point of metals:

1. Most metals have a high melting point and boiling point. For example, iron metal has a high melting point of $1535°\mathrm{C}.$
2. But there are some metals such as sodium and potassium which possess low melting points of $98°\mathrm{C}$ and $64°\mathrm{C}$ respectively. Other metals such as $\mathrm{Gallium}\left(\mathrm{Ga}\right)$ and $\mathrm{Caesium}\left(\mathrm{Cs}\right)$ also have low melting points of $30°\mathrm{C}\mathrm{and}28°\mathrm{C}$ respectively and therefore, they start melting in our hands.

Thus, two metals that possess a low melting point are $\mathrm{Gallium}\left(\mathrm{Ga}\right)$ and $\mathrm{Caesium}\left(\mathrm{Cs}\right)$.
