What happends at the melting point?

Answer 1

The melting point of a solid chemically pure substance is a temperature at which the substance can change from a solid to a liquid phase by absorbing heat, called the "heat of fusion", without any change in the internal temperature of the substance. At any specified ambient pressure, there is only one such temperature for each pure substance.

Answer 2

At the melting point a SOLID turns to a LIQUID. (Increasing temperature).

At the same temperature , when a liquid turns to solid it is referred to as FREEZING POINT.

NB At the boiling point a LIQUID turns to a GAS. (Increasing temperature).

At the same temperature , when a gas turns to liquid it is referred to as CONDENSING POINT.

NNB Carbon Dioxide, a gas, moves directly to a solid(dry ice) . This is called the SUBLIMATION POINT.

Answer 3

At the melting point, a solid substance changes into a liquid state. This transition occurs as the substance absorbs heat energy, causing the intermolecular forces holding the solid structure together to weaken and break down. Once the melting point is reached, the substance can flow freely as a liquid.
