When we talk about matter, it's amazing to see how physical and chemical changes can affect it. Let's break these changes down in a simple way:

Physical Changes

• What It Is: These changes do not change what the substance is made of.
• Examples:
  • Ice melting into water: It’s still water (H₂O), just in a different form.
  • Boiling water: The water changes from liquid to gas but is still the same substance.

Effects on Matter:

• Physical changes can change things like size, shape, or state (solid, liquid, gas) without creating something new.

Chemical Changes

• What It Is: These changes change the way the substance is made.
• Examples:
  • Rust forming on iron: Rust (iron oxide) is different from plain iron.
  • Baking a cake: The ingredients mix together to form a new product that has different properties.

Effects on Matter:

• Chemical changes create new materials and can really change things like color, temperature, or state.

Summary

Both physical and chemical changes show us how matter can change. Physical changes keep the same materials but change how they look or act, while chemical changes turn substances into something entirely new. Each type of change highlights the different ways matter behaves and how we see it in our daily lives!
