Lighter materials like paper, leaves, and wood float on water because they are less dense than water. This means that they weigh less per unit of volume compared to water, allowing them to float. Understanding the concept of density helps explain why certain objects float while others sink.

Why do lighter materials like paper, leaves, and wood float on the sur...
Explanation:
Density:
- The main reason why lighter materials like paper, leaves, and wood float on the surface of water while heavier objects like iron sink is due to their density.
- Density is a measure of how much mass is contained in a given volume.
- Objects that are less dense than water will float, while objects that are more dense than water will sink.
Less dense than water:
- Lighter materials such as paper, leaves, and wood are less dense than water.
- This means that these materials have less mass packed into a given volume compared to water.
- As a result, the buoyant force acting on these materials is greater than their weight, causing them to float on the surface of the water.
Heavier objects:
- Heavier objects like those made from iron are more dense than water.
- Heavy materials have more mass packed into a given volume compared to water.
- The buoyant force acting on these objects is not enough to overcome their weight, causing them to sink in water.
Conclusion:
In summary, the density of an object compared to the density of water determines whether it will float or sink. Lighter materials float because they are less dense than water, while heavier objects sink because they are more dense than water.
