Type in chemical change,

then physical change.

Ah, chemical and physical changes, like Batman and Robin, but with atoms and molecules instead of capes and masks. Let's break it down:

Chemical change is like when your ex transforms from a cheerful cupcake lover into an angry broccoli enthusiast overnight. It involves a modification in the chemical composition of a substance. New substances with different properties are formed. It's like a magical potion turning a pumpkin into a carriage, except in a lab.

On the other hand, physical change is more like changing your hairstyle or ironing your clothes. It's a makeover that doesn't involve altering the substance's chemical identity. Picture a melted ice cube turning into a solid popsicle or a crumpled piece of paper becoming smooth again with just a few strokes. It's all about appearances, my friend.

So, one is a transformation at a molecular level, while the other is more of a superficial alteration. They're like two sides of the same coin, just with different levels of dramatic flair.

A chemical change refers to a process in which substances go through a chemical reaction, resulting in the formation of new substances with different chemical properties. Examples of chemical changes include burning wood, rusting iron, and cooking food. These changes typically involve a rearrangement of atoms and often include the release or absorption of heat or light.

On the other hand, a physical change refers to a process in which substances undergo a change in their physical appearance or state, but their chemical composition remains the same. Examples of physical changes include melting ice, boiling water, and dissolving sugar in water. These changes typically involve a change in the physical properties of a substance, such as its shape, size, or state (solid, liquid, gas).
