Which factor causes a decrease in the rate of dissolution?
garik1379 [7]

Answer:

The correct option of the first option

Explanation:

Dissolution of a solute in a solution is the process in which the solute interacts with the solvent leading to the disappearance of the solute to form a solution. Rate of dissolution is primarily affected by three factors namely

<u>Stirring of the solution</u>: Stirring the solution causes the solute to interact more with the solvent, <u>thus increasing the rate of dissolution</u>.

<u>Surface area of the solute</u>: The smaller the surface area of the solute, the more easier it is for it (the solute) to interact with the solvent. Hence, <u>the smaller the surface area, the faster the rate of dissolution</u>.

<u>Temperature of the solvent</u>: An increase in temperature of the solvent <u>causes the generally causes more things to dissolve in this solvent</u> due to increased energy of molecules in the solvent, which causes the molecules of the solute and solvent to interact more.

A decrease in the amount of solute<u> will reduce the amount of interaction the solute (since it is in lesser quantity) have with the solvent hence the rate of dissolution will also be low (even though a solution will still be formed)</u>.

Answer:

Conduction  

Conduction moves heat through direct sub-atomic crash. A region of more prominent dynamic energy will move nuclear power to a region with lower active energy. Higher-speed particles will crash into more slow speed particles. The more slow speed particles will increment in motor energy subsequently. Conduction is the most widely recognized type of warmth move and happens through actual contact. Models is place your hand against a window or spot metal into an open fire.  

The interaction of warmth conduction relies upon the accompanying components: temperature slope, cross-segment of the material, length of the movement was, and actual material properties. The temperature inclination is the actual amount that portrays the bearing and pace of warmth travel. Temperature stream will consistently happen from most sultry to coldest or, as expressed previously, higher to bring down active energy. Once there's warm harmony between the two temperature contrasts, the warm exchange stops.

Convection  

At the point when a liquid, like air or a fluid, is warmed and afterward ventures from the source, it conveys the nuclear power along. This sort of warmth move is called convection. The liquid over a hot surface grows, turns out to be less thick, and rises.

Radiation

Thermal radiation generates from the emission of electromagnetic waves. These waves carry the energy away from the emitting object. Radiation occurs through a vacuum or any transparent medium (either solid or fluid). Thermal radiation is the direct result of random movements of atoms and molecules in matter. Movement of the charged protons and electrons results in the emission of electromagnetic radiation.
