What has greater density a grape or a paper clip?
Interesting question. Put the grape in water and I believe you will see it floats. It is lighter than water. Now, put a paper clip in water and you will see it sinks. So the paper clip must have a density greater than water. It has a higher density. The weight of the object does not matter. Density is weight divided by volume. You may also be wondering why some fruits float and others sink in water. Fruits contain water and sugar. This alone would make them slightly heavier than fresh tap water. However, in the skin of fruit, there are openings that contain air. Even a little air can compensate for the extra weight of the sugar. There is a second way to answer your question, you can look up the densities of aluminum (what a paper clip is made of) and water (which is approximately the density of the grape). Just enter aluminum and density into Google, and you will find the density of aluminum much higher than water (density ~ 1 gm/cc).
