Increase...by alot.
increase the surface area of a solid means to increase the area of solid
You increase the surface area
No. In fact, if they retain their combined volume, their surface area would increase.
They both increase. The rate of increase of the surface area is equivalent to the rate of increase of the volume raised to the power 2/3.
Increase...by alot.
Examples:- increase the temperature- increase the pressure- stir the mixture- grind the solid solute
to increase the surface area of the solute
to increase the surface area of the solute
Not necessarily just changing the surface area causes the rate to change. Changing the ratio of surface area volume changes the rate at which a solute dissolves in a solvent. If the surface area is larger and the volume of a solute is smaller or the same, then the rate at which the solute dissolves in a solvent increases. If the surface area is smaller and the volume of the solute is larger or the same, then the rate at which the solute dissolves in a solvent decreases.
Reducing particle size results in an increase in surface area. The increase in surface area allows more solvent (water) molecules to interact with the substance, and this increases the rate at which that substance dissolves.
ALL reactions (apart from Nuclear) take place on the surface. By crushing the solid you are increasing the surface area and also the SA/Volume ratio. This increased surface area increases the area available for the dissolution reaction.
The rate of dissolution of a solid is dependent on the surface area reaction. By crushing the cube, the surface area is greatly increased, thus increasing the rate of dissolution.
To increase the surface area of the solute, which allows it to dissolve faster.
As the particle size gets smaller, the surface area increases, and as the surface area increases, the ease with which water can hydrate the particles increases. When it is easier for water to hydrate the molecules, this increases the speed at which the solute dissolves.
Will increase the rate of dissolution and hence how fast the solute is dissolved.
1. increase the temperature of the solvent 2. increase the surface area of the solute 3. increase the agitation and the amount of the solvent
