Density doesn't sink. Density is a property of an object that determines whether it will sink or float in a fluid. An object will sink if it is denser than the fluid it is placed in, and it will float if it is less dense.
Here's a breakdown:
- Density is a measure of how much mass is packed into a given volume.
- When an object is placed in a fluid, it experiences an upward force called buoyancy.
- The buoyancy force is equal to the weight of the fluid displaced by the object.
- If the object's weight is greater than the buoyancy force, it sinks. This happens when the object is denser than the fluid.
- Conversely, if the object's weight is less than the buoyancy force, it floats. This occurs when the object is less dense than the fluid.
Examples:
- A rock is denser than water, so it sinks.
- A piece of wood is less dense than water, so it floats.
