π What are Properties of Matter?
Everything around you is made of matter! Matter is anything that takes up space and has weight. Properties of matter are the special things that help us describe and identify different types of matter. They're like clues that tell us what something is!
π Physical Properties
Physical properties are things we can observe or measure without changing the matter into something new. Here are some examples:
- π Color: π¨ The way an object looks, like red, blue, or green.
- 𧱠Shape: π The form of an object, like round, square, or pointy.
- βοΈ Mass: π How much 'stuff' is in an object (we often measure this as weight).
- π‘οΈ Temperature: π₯ How hot or cold something is.
- π§ Volume: π¦ The amount of space an object takes up.
- β¨ Texture: ποΈ How something feels, like smooth, rough, or bumpy.
π§ͺ Chemical Properties
Chemical properties describe how matter changes when it interacts with other matter. This usually involves creating something new!
- π₯ Flammability: π₯ Whether something can burn.
- π Reactivity: π§ͺ How easily something reacts with other substances (like if it rusts or bubbles when mixed).
π§ States of Matter
Matter can exist in different states, and these are also properties!
- π§ Solid: 𧱠Has a definite shape and volume (like ice or a rock).
- π§ Liquid: π Has a definite volume but takes the shape of its container (like water or juice).
- π¨ Gas: π Has no definite shape or volume and can spread out (like air or steam).
