Study Notes
States of Matter
- Matter is anything that has mass and takes up space.
- Matter exists in different shapes, sizes, and forms.
- Examples of matter include ice cream, root beer, and carbon dioxide gas.
- Matter is made of tiny particles that are too small to see.
- A microscope is needed to view individual particles.
- Properties of matter can be observed (e.g., size, color, shape)
- Properties can also be measured (e.g., mass, volume)
- Matter can exist in three states: solid, liquid, and gas.
Solid State
- Solids have a definite shape and volume.
- Examples of solids include books, tables, and pencils.
- Particles in solids are closely packed together and move very little.
Liquid State
- Liquids have a definite volume but take the shape of their container.
- Examples of liquids include milk, orange juice, and water.
- Particles in liquids are close together but can move around.
Gas State
- Gases have neither a definite shape nor a definite volume.
- Gases fill the entire space of their container.
- Examples of gases include air in a balloon.
- Particles in gases are widely spaced and move quickly.
Particle Movement
- Particles in matter are always moving.
- The speed of particle movement varies between states.
- In solids, particles vibrate but don't move around much.
- In liquids, particles move around more freely than in solids.
- In gases, particles move very rapidly and randomly.
Matter Classification
- Physical properties can be observed and measured.
- Examples of physical properties are size, color, and shape.
- Matter can be classified based on physical properties.
Dissolving
- Some matter can disappear into other matter (e.g., sugar dissolving in water).
- Dissolving is spreading evenly in a liquid, making a solution.
- Dissolving can be observed when sugar is added to coffee.
