Not necessarily, the melting point is usually just the point at which the solid will begin to transform into a liquid. There is usually a melting point range for most solids, meaning the temperature range the solid will completely melt. However, if the solid is extremely pure the range will be very small (only 1-2 degrees Celcius) therefore different books report different melting points for various solids. The Merck Index is a really reliable source for anything to do with any substance, be it physical properties such as melting point, to chemical properties such as reactivity.
What else can I help you with?
is the melting point the temperature at which you given liquid changes to gas?
The melting point is the temperature at which a solid becomes a liquid.
Are the melting point of solid and freezing point of liquid of a substance different?
yes the melting point of solid and freezing point of liquid of a substance is differ but in the case of water the melting and freezing point is same.
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 does a melting point of a substance indicate?
It indicates that the substance has turned to a liquid.
How are melting point and solidification point related to each other?
The melting point and solidification point of a substance are the same. They are the point of transition between solid and liquid. This temperature is the melting point if the substance starts out solid and is the solidification point if the substance starts out liquid.
What is the difference of melting and freezing?
When solid is converted into liquid then it is melting and when liquid is converted into sold it is freezing although Melting and Freezing point for a substance is the same.
Are melting and boiling points of a substance the same?
The melting and boiling points of a substance (in this case I am assuming you are referring to a pure substance, and not a mixture), are the same. The triple point is defined by the temperature and pressure at which solid, liquid, and vapor of a substance, can coexist in equilibrium. At any pressure below the triple point, only sublimation and condensation are possible (no liquid phase is possible). Between the triple point pressure and the critical point pressure, there is a difference between the melting and boiling points, of a substance. The melting point temperature will be lower than the boiling point. At the critical point, the densities of the liquid and vapor phases, have merged, and boiling no longer occurs. At and above the critical point, you cease to get liquid and vapor, but you get what is referred to as a "supercritical fluid".
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.
What do you call the temperature at which a solid changes to a liquid?
This is the melting point.
What is the melting point of liquid nitrogen?
Liquid nitrogen has no melting point. A melting point is the temperature when a solid turns into a liquid. Since liquid nitrogen is already a liquid, it has no melting point. It is already melted, compared to solid nitrogen.
Is a condensation point the same as a melting point?
No, Gas--->liquid (condensation). Solid---->liquid (melting)
Which term is defined as the temperature at which a substance changes from a solid to a liquid state?
The term defined as the temperature at which a substance changes from a solid to a liquid state is called the melting point.
If a substace is a liquid already what would it be before the melting point?
It would be solid before it reached the melting point. If it is liquid, it has already reached the melting point.
is the melting point the temperature at which you given liquid changes to gas?
The melting point is the temperature at which a solid becomes a liquid.
What is a temperature at which solids start to change from a liquid?
The temperature at which a solid starts to change into a liquid is called the melting point. At this point, the solid absorbs enough heat energy to overcome its intermolecular forces and transitions into a liquid state.
How are boiling point and melting point different?
Boiling point is the temperature point at which a liquid becomes a gas while melting point is the point at which a solid becomes a liquid.
Are the melting point of solid and freezing point of liquid of a substance different?
yes the melting point of solid and freezing point of liquid of a substance is differ but in the case of water the melting and freezing point is same.
