# Does the melting point and freezing point of a substance occur at the same temperature?

You may think the melting point and freezing point of a substance occur at the same temperature. Sometimes they do, but sometimes they don't. The melting point of a solid is the temperature at which the vapor pressure of the liquid phase and the solid phase are equal and at equilibrium. If you increase the temperature, the solid will melt.

### Why are melting point and freezing point the same ?

The two terms mean the same thing--the temperature at which the state of a substance changes from a solid to a liquid, or vice versa. When it goes from solid to liquid, we refer to "melting point";

Does freezing point and melting point reversible and occur ? The melting process always occurs at the same temperature. The freezing process, however, does not. Freezing is aided by nucleation points (typically bits of impurity). If such nucleation points are available, freezing occurs at the same temperature as melting.

What happens to a substance when it freezes and melts ? Freezing and melting are the same process and occur at the same point in temperature; whether the temperature is lowering or rising determines if something is freezing or melting. What's curious

### Why is the melting point and freezing point the same ?

The freezing point is the same temp as the melting point, it just depends on which direction you are going and whether you are adding or taking away heat. The condensation point is the same as the

Characteristic Properties Flashcards Quizlet? *The temperature at which a solid turns into a liquid while heat is being added. *Melting point is the same temperature as freezing point.

What Is the Definition of Melting Point? The freezing point and the melting point do not necessarily occur at the same temperature. This is because some substances (e.g., water) experience supercooling, so they may freeze at a temperature much lower than they melt. So, while melting point is a characteristic property of a substance, the freezing point is not.

### How do freezing and melting of water occur at the same ?

It’s not just water, it’s for everything. The differnce between melting temperature and freezing temperature is only one of perspective. At that temperature, there’s an equilibrium between solid and liquid. If you were coming from a solid, you call that melting.

What is the major difference between melting and freezing? Freezing and melting.Freezing is the change that occurs when a liquid changes into a solid as the temperature decreases.Melting is the opposite change, from a solid to a liquid as the temperature increases. These are both examples of changes in the states of matter of substances.

What is the process of melting and freezing? Why does melting and freezing occurs at the same temperature? Melting occurs when a solid is heated and turns to liquid. Hence, the melting point and freezing point of a substance are the same temperature. The melting and freezing point of a substance are defined as the temperature above which, the substance is liquid and below which, it is solid.
