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.
The correct answer is option a, that is, Vitamin K.
Vitamin K is primarily produced by the bacteria in the large intestine. The dietary sources include the green photosynthetic parts of the plants. The vitamin plays an essential role in the development of many blood-clotting factors in the liver, and their deficit can result in bleeding disorders.
