The increase in area of the solid on heating is called Superficial expansion
We increase the surface area of a solid when dissolving to speed up the dissolution process. This is because a larger surface area allows for more contact between the solid and the solvent, leading to faster and more efficient dissolution. Additionally, increasing the surface area can also help achieve a more uniform dissolution throughout the solid.
To dissolve more solid solute in a liquid, you can increase the temperature of the solvent, stir or agitate the solution, increase the surface area of the solute by crushing or grinding it, or increase the pressure of the system if the solute is a gas. These methods help to overcome the forces holding the solute particles together and facilitate their dispersion in the solvent.
Stirring or agitating the solution to increase contact between the solid and solvent, increasing the temperature of the solvent which generally increases the solubility of solids, and reducing the particle size of the solid to increase surface area available for dissolution.
It exposes more of the solid to whatever you want to mix it with so that whatever you are doing, whether it be a physical or chemical change, will take place more rapidly.
Stir the solid in the liquid vigorously to maximize contact and facilitate dissolution. Increase the temperature of the liquid, as higher temperatures generally enhance solubility. Crush the solid into smaller particles to increase the surface area for better dissolution.
increase the surface area of a solid means to increase the area of solid
To increase the rate of a reaction involving a solid, you can try increasing the surface area of the solid by breaking it into smaller pieces or grinding it into a powder, which exposes more surface area for the reaction to occur. Another way is to increase the temperature, as higher temperatures generally lead to faster reaction rates. Additionally, using a catalyst can also help to speed up the reaction.
You increase the surface area
Temperature and particle size of the solid will affect both the rate of dissolving and the solubility in a liquid. Higher temperatures generally increase the rate of dissolving and solubility, while smaller particles increase the rate of dissolving due to increased surface area available for interaction with the solvent.

heating, stirring, surface area
Superficial expansion is the increase in surface area of 1 meter square area of a solid for rise of temperature, 1kelvin is called the coefficient of surface expansion of material of that solid.
It will increase it, as more of the outer surface of the solid is incontact with the liquid that it is dissolving in. :)
The process of changing from a solid to a gas is called sublimation. In sublimation, a solid directly transitions to a gas without passing through the liquid phase. This is usually achieved by heating the solid substance to its sublimation point, where it bypasses the melting phase and goes directly into the gas phase.
Examples:- increase the temperature- increase the pressure- stir the mixture- grind the solid solute
