Question

In your lesson today you learned that items can be dissolved faster when

Question 2 options:

adding heat


smaller particle size with greater surface area


stirring


all of the above

Answer 1

Items can be dissolved faster when adding heat in the process, when the size of particle is small but the surface area is very large in the process, when stirring is used to mix the solution or to increase the rate of reaction.

Explanation:

All the above methods are correct and useful to increase the dissolving rate of items in a process or reaction. By increasing heat the rate of reaction increases gradually because the heat provides energy to the molecules and force them to leave the shell and react rapidly.

When having a large surface area the dissolving time gradually decreases because the size of the particle is comparatively smaller. Stirring helps in mixing the solution due to which the molecules reacts fast and the item’s reaction and dissolving time gradually decreases.
