when u have a damp crystal then water molecules act as impurities and break bonds between molecules of solid in order to find a place there. thus the ordered arrangement of the crystal gets disturbed as at some places water may get connected with atoms of crystals as shown below and hence due to lower forces of attraction at bonds become weaker and it takes less amount to break them. hence melting point gets lowered.

What is the physical change of a solid at the melting point?
It turns from a solid to a liquid
The temperature at which a solid melts is called?
melting point
What becomes solid above the melting point?
assuming it is its own melting point NOTHING which is why its a MELTING point
Does matter change from solid to liquid at freezing point or at melting point?
Matter changes from solid to liquid at its melting point, because this change is called melting. Freezing point is about the same as melting point, but it can be slightly lower, so melting point should always be used.
What point does a solid turn into?
A solid turns into a liquid at its melting point.
What do you call the temperature at which a solid changes to a liquid?
This is the melting point.
How does a contaminant affect the melting point of a solid?
A contaminant reduces the melting point of a solid.
What is the physical change of a solid at the melting point?
It turns from a solid to a liquid
The temperature at which a solid melts is called?
melting point
Which term is defined as the temperature at which a substance changes from a solid to a liquid state?
melting point
Which solid is more likely to have the lowest melting point an ionic solid or molecular solid?
Molecular Solids have a lower melting point
What becomes solid above the melting point?
assuming it is its own melting point NOTHING which is why its a MELTING point
Does matter change from solid to liquid at freezing point or at melting point?
Matter changes from solid to liquid at its melting point, because this change is called melting. Freezing point is about the same as melting point, but it can be slightly lower, so melting point should always be used.
What is high melting point?
The melting point of a solid is the temperature at which it changes STATE from SOLID to LIQUID. At the melting point the solid and liquid phase exist in equilibrium. The melting point of a substance depends (usually slightly) on pressure and is usually specified at STANDARDatmospheric pressure.
What physical change of a solid to a liquid at the melting point?
The physical change of a solid to a liquid at the melting point called melting.
What point does a solid turn into?
A solid turns into a liquid at its melting point.
When a solid is heated to its melting point what happens?
The intermolecular forces of attraction in the solid decreases as it is heated and the solid melts (solid converts to liquid) at its melting point.
