What is the fundamental difference between a chemical reaction and a physical change?


In a chemical reaction, substances are transformed into new substances with different chemical compositions and properties. Bonds between atoms are broken and new bonds are formed, resulting in the creation of entirely new molecules or compounds. This change is often accompanied by a release or absorption of energy, such as heat or light. The original substances cease to exist in their previous forms, and new substances are produced. Chemical reactions are typically not easily reversible.


On the other hand, a physical change involves a change in the physical state or appearance of a substance without altering its chemical composition. This means that the molecules and atoms of the substance remain the same before and after the change. Common examples of physical changes include changes in state (solid to liquid, liquid to gas, etc.), changes in shape or…

Imagine you're in a swimming pool and you have a ball made of metal and another ball made of foam. When you drop these balls into the water, something interesting happens. The metal ball sinks right to the bottom, while the foam ball floats on the surface.

Now, let's talk about why this happens. It's all about something called "buoyancy." Buoyancy is the force that makes objects float or sink in water (or any other fluid).

Here's how it works: Every object, whether it's big or small, heavy or light, has something called "density." Density is a measure of how much stuff is packed inside an object. For example, metal is denser than foam because it has more stuff inside it, and foam is less dense because it has less stuff inside.

When you…
