Why does the temperature become constant at the point of melting till the whole substance of a solid melted?

That happens because any heat that is added to that melting material will be used to cause further melting, until there is nothing left to melt, at which point the added heat can raise the temperature. A solid melts at its melting point; it does not get hotter than the melting point without melting, that's why it is the melting point.

What point does it become a liquid?
The boiling point of a substance is the point at which that substance will change between being a gas and a liquid. For example, the boiling point of water is 100oC, so water vapour will change to water at this temperature. The boiling point of Methane is -161oC, so any temperature above this, Methane will be in gas form.
What is melting points and the boiling points?
Melting point: the temperature at which a solid become a liquid. Boiling point: the temperature at which a liquid become a gas.
What temperature does a solid becomes and liquid?
The temperature varies in each substance. When liquids become solids, we call this the freezing point (liquefaction point) and when they become liquid, we call this the melting point (crystallization point). These two points are NOT exactly the same in all cases but in most.
How is the melting of an impure compound expected to change with recrystallization?
The melting point of an impure compound will become closer to that of the actual melting point of the pure substance with recrystallization of your mixture.
What does melting and boiling point mean?
The relative temperature at which a group of solids change into liquids is known as relative melting point. As heat increases, the solid slowly changes its state as it melts. Melting of ice to water is an example for melting point.
How is melting point of a substance defined?
This is the temperature when a solid become a liquid.
What substance become a liquid when his temperature is above 0 degrees Celsius?
Any substance with a melting point above this given temperature.
Which is true of a melting point and a boiling point?
Melting point: at this temperature a solid become a liquid.Boiling point: at this temperature a liquid become a gas.

What is melting points and the boiling points?
Melting point: the temperature at which a solid become a liquid. Boiling point: the temperature at which a liquid become a gas.
Melting point of solid?
The temperature at which the kinetic energy overcomes the intermolecular forcesThe temperature at which the kinetic energy overcomes the intermolecular forces
What substance can be converted from liquid to solid and can not be converted back to liquid?
There is no such substance. Because only a transformation of physical state is taking place. Let me expand: Every substance has a specific temperature at which it changes its physical state. The temp. at which the substance turns into liquid is known as melting point and the temp. at which the liquid turns to solid is known as freezing point. Usually the melting point and the freezing points of a substance are the same. (But there are certain exeptions to this rule.) So if the temperature at which the substance turns into liquid is acheived i.e the melting point - then it definitely would become liquid again.
When you reach the temperature of what point you become a liquid.?
melting
What are the melting and boiling points of different substances?
At 1atm, the melting point of H2O(water) is 0 degrees celcius and the boiling point is 100 degrees celcius. Carbon dioxide's boiling point is at -25 degrees and so its meting point. Since it crystallises and sublimates, it has no liquid form. The boiling- and melting points of elements/compounds depend on the amount of pressure exerted on the element/compound. Generally, the higher the pressure, the higher the boiling and melting points. All except for water, gallium and bismuth. These substances' melting point decreases as pressure increases.
What is the melting point Freezing point?
Freezing and melting points are synonyms: at this temperature a solid become a liquid or a liquid become a solid.
At what temperature does liquid become solid?
At its melting point. For example, the melting point of ice is 0 degrees celsius, so ice (solid) will melt to become water (liquid) at this temperature.
What temperature does a solid becomes and liquid?
The temperature varies in each substance. When liquids become solids, we call this the freezing point (liquefaction point) and when they become liquid, we call this the melting point (crystallization point). These two points are NOT exactly the same in all cases but in most.
