What are the factors that affect the rate of dissolution? a. color, temperature, stirring b. texture, surface area, stirring c. temperature, stirring, surface area d. stirring, temperature, texture

Option (C) is the correct answer.

When solute is added to the solvent, results in the formation of solution and the process is said to be dissolution.

Dissolution process depends upon the three factors: temperature, stirring and surface area.

Stirring increases the rate of dissolving as when stirring a solute in the solvent, stirring helps in the distribution of solute throughout the solvent which results in speed up the dissolving rate.

Dissolution also depends upon the temperature, in warm solvent, solute dissolves readily whereas in cool solvent, solute dissolves slowly as particles have more movement energy.

Greater the surface area, there will be more contact between the solute particles and solvent particles which increases the rate of dissolving. Smaller the surface are, there will be less contact between the particles which decreases the rate of dissolving. For example: granulated sugar dissolves more readily due to larger surface area and one ice cube dissolves slowly due to smaller surface area.

Hence, rate of dissolution depends upon temperature, stirring, surface area.

in cartography, a contour line (often just called a "contour") joins points of equal elevation (height) above a given level, such as mean sea level. a contour map is a map illustrated with contour lines, for example a topographic map, which thus shows valleys and hills, and the steepness or gentleness of slopes.
