Let’s drive into the Melting and Dissolving processes.  

Melting vs Dissolving  

The difference between Melting and Dissolving is that Melting is a process that physically transmits the phase of a substance. Dissolving is a chemical process where two substances are involved in solution establishment. The melting process involves a single solidity and, the Dissolving process involves double materials.  

Melting vs Dissolving

Melting is a physical process where a substance changes its phase. Melting is known as fusion over other words.

The Melting Process used to liquefy the substances by heat. By applying the heat or pressure, the internal energy of the solid substance will increase and, it tends to reach the melting point.

In Science, it had explained that solid substances interchange it phase when the temperature had amplified.  

Dissolving is different from melting. Dissolving is a chemical process where two substances form a single solution.

Another name of Dissolving is Dissolution. A solid material usually combines with a liquid phase particle to forms a compound and, this process was known as the Dissolving process.

Two substances used to become fluid is known as Dissolving.  

Comparison Table

Parameters of Comparison Melting  Dissolving 
Melting is a process where a single substance changes its phase. Dissolving is a process where two different substances involve and forms a solution. 
Process type    
Melting is a physical process.  Dissolving is considered primarily as a chemical process.  
Process Involved    The substances had liquefied by applying to heat.  A solid particle and a liquid combine to form a Fluid solution.   
Difference    In the melting process, there is no use with solute and solvent   Dissolving involves the solute and solute in the process.  
Example  Ice cream changing its phase into liquid.  Unfreeze of Ice cubes. Adjoin sugar into the water.   Here sugar is a solute along the water are the solvents. 

What is Melting?  

Melting is a process where a single substance changes its phase by heating. Melting is also known as fusion.

The internal energy of a solid material will increase when the temperature or pressure had applied. The intransitive verbs of the Melting are melts, melting and melting.

To unfreeze 1g of ice, 334J of energy possessed to require at 0-degree temperature and, this process is known as latent heat of melting. The opposite process of Melting is Freezing.

The Melting process is chief for chemical research and, the solid’s melting point had tested under normal conditions. The Melting Point is paramount for the storage and transport of solid particles.

Solutes and Solvents did not involve in the melting process. The Melting process had used to identify the substances.

The melting point range had required because all the solids do not melt at a specific temperature. Melting Points are different for various solids.   

When impurities lie in the solid substances, the Melting Point Depression had used to lower the impurities in solid substances. A few of the related examples are:  

  • Melting of butter by heating.  
  • Candle melting when it is lightening up.  
  • Melting of steel and it needs high temperature for melting.  
  • Melting of Gallium and can be melting at room temperature.  

The particles will vibrate faster because the solid gains energy when the solid particle had heated and, the solid start melting and converted into liquid. This is happening in Melting Process.  


What is Dissolving?  

Dissolving is a chemical process where a solid particle and liquid combine to form a solution. Solvents and Solutes involve in the dissolving process.

Solid particles had considered solutes and, Solvents are the solvents. Dissolving gives the fluid products.

Another name of Dissolving is Dissolution. Dissolving is different from Melting.

Dissolving involves physical processes, but most solutions are considered Chemical processes. If the dissolving process had favoured, then the substance is told to be soluble in the particular solvent.

Dissolving solidities were in liquid form. The dissolved solutions will not be separable with the filtration process.

Dissolving involves 3 steps to form a solution;  

  1. It separates the particles of the solute.  
  2. Separating the solvent particles from each other.  
  3. Now a new solution takes place by combining the solute and solvent particles that had separated.  

Dissolving had occurred when the larger particles of a solute break down into smaller particles to form a new solution. Some of the examples are;  

  • Salt and water combination, here salt is a solute along the water is a solvent.  
  • Stirring the solute like sugar in the solvent like water.  
  • Chromium and Iron had dissolved to form the stainless-steel products.  
  • Sugar, dissolved carbon dioxide is the solutes dissolve with water to form Soda solution.  

The interaction of atoms in the dissolving process is a chemical reaction.   


Main Differences Between Melting and Dissolving  

  1. Melting is a process that occurs with a single substance where two substances with different phases involved in the Dissolving process.  
  2. Both Melting and Dissolving give the liquids as products, Melting is a physical process, where Dissolving is a chemical process.  
  3. Solutes and Solvents are taking place in the dissolving process. In contrast, Solutes and Solvents do not involve in the melting process.  
  4. A high range of temperatures and pressures had required to melt the large scale of solids. On the other hand, solute and solvent combine to form a solution.  
  5. Ice cubes turn into liquid phase is an example of the Melting Process. Salt solute combining with water is an example of the Dissolving process.
