The transition from solid to liquid is a state change. Its ability to flow changes.
The physical property of water that changes when it reaches its melting point is its state of matter. At the melting point, water changes from a solid (ice) to a liquid form.
balance
It boils: the liquid changes to gas phase.
The atoms start to move around more quickly and when the solid reaches it's melting point it will turn into a liquid.
Well, when the thermal energy of a substance increases, the temperature increases. When the temperature reaches the boiling or melting point, the state of the matter changes from one to another.
When you heat ice it takes in the heat and its temperature rises until it reaches melting point. It then takes in heat without getting hotter. When it's all melted, then the water that it now is gets hotter and hotter. When it reaches boiling point more heat will simply turn it into steam without it getting hotter. If you keep adding heat to the steam then it will get hotter. The heat that you have to add to something to change its physical state (i.e. from solid to liquid or liquid to gas) but without it actually getting hotter, is known as 'latent heat'.
Its physical state. When it reaches its melting point, it will change from a solid to a liquid.

When a substance reaches its melting point it changes from solid to liquid. When a substance reaches its boiling point it changes from liquid to gas.
Solid changes to liquid when a substance reaches it's melting point. For example, water's melting point is 0 degree celcius.
Substances have different melting points. When a substance reaches it melting point it will begin a phase change. Wikipedia's chart for elements of melting points. http://en.wikipedia.org/wiki/List_of_elements_by_melting_point
When a liquid reaches boiling point it goes through a phase change, liquid to gas. Phase changes do not change the nature of a chemical so it is a physical change. This physical change can sometimes be caused by a chemical change though.
No, freezing changes a liquid to a solid. To change a solid to a liquid you need to apply heat. The change begins when the solid reaches its melting point.
Both a chemical and physical change occurs.
The incipient melting point refers to how metal is heated. It is the point just before the metal reaches its melting point.
Liquid.
catchy slogan is that which reaches to heart. and also is to the point
it melts =) and becomes a liquid
