Hello there! As a subject matter expert in physics and materials science, I'm here to provide you with a comprehensive answer to your question regarding what sinks and what floats.
Firstly, it's essential to understand the concept of density. Density is defined as the mass per unit volume of a substance. The formula for density is:
\[
\text{Density} = \frac{\text{Mass}}{\text{Volume}}
\]
When we talk about objects sinking or floating, we're essentially discussing the relationship between the density of the object and the density of the fluid it's placed in. The principle at work here is Archimedes' Principle, which states that any object, wholly or partially immersed in a fluid, is buoyed up by a force equal to the weight of the fluid displaced by the object.
Now, let's delve into the specifics:
1. Sinking Objects: An object will sink if its density is greater than the density of the fluid it's in. This is because the weight of the fluid displaced by the object is less than the weight of the object itself. The object will continue to sink until it displaces a volume of fluid whose weight is equal to its own weight.
2. Floating Objects: Conversely, an object will float if its density is less than the density of the fluid. In this case, the weight of the displaced fluid is greater than the object's weight, causing it to float.
3. Molecular Packing: The statement that objects with tightly packed molecules are denser and sink, and those with more loosely packed molecules are less dense and float, is a simplification. While it's true that the arrangement of molecules can affect density, it's not the sole determining factor. The density of an object is influenced by both the mass of its molecules and how closely they are packed together.
4. Types of Materials: Different materials have different densities due to differences in molecular structure and atomic mass. Metals, for example, have high densities because their atoms are tightly packed and heavy. On the other hand, materials like wood or foam have lower densities because their molecular structure allows for more space between the molecules.
5. Shape and Size: The shape and size of an object can also influence whether it sinks or floats. A larger object with the same density as a smaller one will displace more fluid and may be more likely to float.
6. Conditions: The conditions of the fluid can affect buoyancy as well. For example, the temperature and salinity of water can alter its density, which in turn can affect whether an object sinks or floats.
7.
Applications: Understanding the principles of sinking and floating is crucial in various fields, from shipbuilding and submarine design to understanding the behavior of oil and gas in the ocean.
In conclusion, whether an object sinks or floats is determined by its density in relation to the fluid it is in, and this is governed by Archimedes' Principle. The molecular packing is a factor that contributes to the overall density, but it's not the only one. Other factors such as the material's atomic mass, molecular structure, and the object's shape and size also play significant roles.

Objects with tightly packed molecules are denser and sink.Objects with more loosely packed molecules are less dense and float. Whether an object sinks or floats depends on its density. Everything is made of molecules.
