Question

Near the melting point of a solid, the heat supplied does NOT raise the temperature. Instead, what does it do?

पर्याय

• Increases the volume of the solid rapidly

• Weakens the bonds between particles

• Converts the solid directly into gas

• Decreases the kinetic energy of particles

Answer 1

Weakens the bonds between particles

Explanation:

Near the melting point, the heat energy supplied is used to weaken and break the bonds between particles rather than increase the temperature. This is why the temperature remains constant at the melting point even as heat is being absorbed.
