Many plastics float in water. Do you think this is an advantage or disadvantage? Why? PLEASE HELP IT IS A MAJOR GRADE QUESTION!
That would have to depend on how the plastic was to be used, wouldn't it? If, for example, you wanted to place a marker in the water so you know where your crab trap was set, you would want it to float. If, on the other hand, the crab trap was made of plastic and you wanted it to stay on the bottom, you would want it to sink. So the answer to your question really depends on the use to which the plastic will be put.
advantage if you drop something plastic, it will float. plastic boats are lighter, so its much more conveinent. if someone dumps their garbage in a river or something, the plastics will float, so it will be easier to get out, because they are whats most harmful to the animals etc.
