The Melting point and Freezing point are both temperatures at which one state gets the change to another state. The actual compound at these temperatures gets converted into a different combination.
Key Takeaways
- The melting point is the temperature at which solid changes into a liquid, whereas the freezing point, is the temperature at which a liquid changes into a solid.
- The melting point of a substance is higher than its freezing point because it requires more energy to break the intermolecular bonds between the solid particles than to create them during freezing.
- A substance’s melting and freezing point are the same under standard conditions and are characteristic physical properties of a substance that can be used to identify it.
Melting Point vs Freezing Point
The melting point occurs when the state of the substance changes from solid to liquid, but the Freezing point occurs when the juice changes into a solid when the vital heat is removed. The melting point can be observed when the temperature increases, and Freezing Point can be observed when the temperature decreases.
The melting point occurs when the substance changes and turns solid to liquid. Heat is given to the meaning.
It ultimately forms a solid when it reaches its freezing point. The substance freezes and melts at the same temperature.
Comparison Table
| Parameters of Comparison | Melting Point | Freezing Point |
|---|---|---|
| Definition | Solid turns liquid at a particular temperature. | Liquid changes to solid at a particular temperature |
| Process | The process is called melting. | The process is called freezing. |
| Heat | Supplied from external sources | Taken away from the substance |
| Volume | Increases | Decreases |
| Internal Energy | Increases | Decreases |
| Examples | Solid to liquid wax | Water turns ice |
What is Melting Point?
The melting point of the crystalline compounds defines pure compounds and elements of the solid. External sources are required to give heat to the stable so that the heat will raise the reliable’s temperature and finally turn into liquid.
The Melting point of the crystalline compounds defines pure compounds and elements of the solid. The solid’s internal energy keeps increasing when the stable gets heated.
The impurity in the substance affects its melting and freezing temperature. The molecules move more when the temperature rises.
External pressure is one of the factors why the substance reaches its melting point. Crystalline compounds have a constant melting point.
The transition from solid to liquid is so low. An example of a Melting point is stable oxygen has a melting point of -218.4 degrees celsius.
What is Freezing Point?
The Freezing point occurs when the substance undergoes changes and gets converted from liquid to solid. When the heat of the solid is taken away, the heat inside the stable keeps on decreasing, which results in a substantial change into a liquid.
The substance freezes and melts at the same temperature. It is a physical process. It is a reversible process.
This change occurs in a high-state energy state and then moves to lower-state energy. The molecules have to move less due to a decrease in their temperature.
The impurity in the substance minimizes the freezing point. This is a good indication of purity. The purity of the substance can be defined using an excellent issue.
Main Differences Between Melting and Freezing Points
- The melting point occurs when the substance changes its state and turns solid to liquid, but the Freezing point occurs when the meaning changes and gets converted from liquid to solid.
- Atmospheric pressure is a significant factor in melting point, but external pressure is a major factor in freezing point.
