Would you be able to plot this graph
An object floats in water if it less dense than water. In other words if the volume of the material weighs less than the same volume of water (for example a piece of plastic). An object sinks in water if it is more dense than water (for example a piece of steel). The same principle applies for objects surrounded by air. Objects that are less dense than air, i.e., weigh less than the same volume of air, will float upward. For example, a helium-filled balloon floats upward because the helium inside the balloon weighs less than the same volume of air, since helium molecules weigh less than the nitrogen and oxygen that make up most of our atmosphere. Objects that are more dense than air, like humans, sink to the bottom of the atmosphere. Suppose we put some air in a sealed, flexible container like a balloon. No air can enter or leave the container, but since the container is flexible, it can easily change its size or volume. At first, the air temperature, air number density, and air…
