Question 12

Answer 1

Answer:

Increasing the surface area of a solid has no effect on the speed of dissolving. Hence, the correct answer is option B.

Explanation:

The increasing of surface area has no effect on the speed of dissolving at as it is irrelevant with the dissolving speed with the solvent. The dissolving effect air speed can be altered with the temperature and with the volume but is increasing of surface area has no relevance on the dissolving speed.

If the temperature is raised above the room temperature it helps in dissolving speed and dissolving quantity. The increase of surface area can we done by various ways such as expanding through mechanical method, etc.  

Answer 2

Increase the speed of dissolving

Explanation:
When they solid and liquids react, it will speed up the dissolving.
