Question

Silver is a substance that expands on melting, so, its melting point ____ when pressure is raised

Answer 1

The effect of melting point with pressure will depend upon the type of substance under consideration.

• If a substance expands on melting, the applied pressure will prevent the substance from melting and results in an increase in the melting point.
• And If a substance contracts on melting, the applied pressure will support the substance for melting and result in a decrease in the melting point.

As the statement says silver expands upon melting therefore its melting point increases with an increase in pressure.

Therefore, silver is a substance that expands on melting, so its melting point increases when pressure is raised.
