What are chemical properties?

Chemical properties are what happens to a material when it changes into something else.

Imagine you have two types of playdough: one is soft and squishy, and the other is hard like a rock. If you put them in the oven, the soft playdough might melt and turn into goo, while the hard one stays solid or maybe cracks. This shows their chemical properties, how each reacts when it's heated.

When something changes from one thing to another (like playdough melting), its atoms are rearranging themselves. That means new stuff is being made, like goo instead of dough. These kinds of changes depend on the material’s chemical properties, not just how it looks or feels.

Think about a matchstick. When you strike it against a rough surface, it lights up and burns, this is because of its chemical property called flammability. The matchstick changes from wood to smoke and ash, showing how flammable it is.

So, chemical properties tell us what happens when materials change into new things, just like how playdough or a matchstick behaves under different conditions.
