Answer:
1. gravel of the sand: a part is dissolved and the remainder is grouped at the bottom of the beaker.
2. drop of sunflower oil: It is not absorbed and heaps on the surface of the water contained in the beaker.
Explanation:
Gravel of the sand is a polar substance. This means that this substance has the ability to dissolve and mix with water in a system in which both were placed together, such as a beaker, for example. However, the beaker limits the amount of water, which limits its ability to dissolve polar substances. Therefore, depending on the quantity, the gravel of the sand, when placed in a beaker with water, will dissolve, in parts, what is not dissolved will accumulate in the bottom of the beacker, because the gravel of the sand is denser than the water.
With the drop of sunflower oil the exact opposite happens. This is because drops of oil are nonpolar substances, which means that they do not have the ability to be dissolved in water. This means that when dropped into the beaker with water, the drop of sunflower oil will not dissolve, but will pile up on the water surface, because it is less dense than water.
Answer: Not likely
Explanation:
Hurricanes can be devastating if they make landfall in an area and even if they do not, can cause excessive rainfall that can lead to flooding in other areas. One of such areas is Maryland.
Even though Maryland has seen its fair share of effects from hurricanes, tropical storms and tropical depressions, there has not been a single storm making landfall at hurricane intensity in Maryland since the mid twentieth century. Hurricane Agnes for instance, caused the deaths of 19 people due to the floods it caused.
