Question

Name two solids whose melting point is less than the boiling point of water

Answer 1

Any two solids whose melting point is less than the boiling point of water are sodium and gallium.

The melting point is the temperature at which a solid is converted into a liquid.

At its melting point, the disruptive vibrations of the solid particles overcome the attractive forces operating within the same.

And as with boiling points, the melting point of a solid is dependent on the strength of those attractive forces.

Sodium chloride an ionic compound that consists of a multitude of strong ionic bonds which melts at 801°C. Ice.

And the melting point of ice is 0°C.
