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.
Explanation:
When sandstone is overlaid by layers and layers of sediment, it becomes subject to enormous pressure and temperature beneath the layers and its grain structure begins to change. The force of compactness causes grain structure and size to reform. This is called metamophism., The sandstone becomes a new rock called quartzite. The two rocks will have different properties. Quartzite will have larger crystals and will be hard and smooth while sandstone will be coarse and soft.
