Question
Why does this happen?
What you see in the picture.
Solution
The picture shows two things that are present in the tub of water. One is a balloon that floats on the surface of the water while the other is an apple that sinks to the bottom of the tub. The balloon floats on the surface of the water because it has less density as compared to the density of the water whereas the apple sinks to the bottom of the tub because it has more density than water.
