Study Notes
- Matter is everything that can be seen and felt.
- Scientists classify matter into three states: solids, liquids, and gases.
- The way matter behaves defines its properties.
Solids
- Have a fixed shape and volume
- Cannot be compressed or poured
- Particles are arranged in a fixed pattern
- Particles are held together strongly and are tightly packed
- Particles vibrate (make small movements) but stay in the same place
- Cannot flow
Liquids
- Take the shape of their container
- Can be poured, but cannot be compressed
- Have a fixed volume that doesn't change, regardless of the container
- Particles touch each other but can move past one another
- Particles are held together weakly, allowing them to move around
Gases
- Flow like liquids and fill any closed container
- Volume can change and are very easy to compress
- Weigh very little, are often invisible, but can sometimes be smelled
- Particles do not touch each other and are far apart
- Particles spread out and move quickly in all directions
Particle Theory
- Matter is made of tiny particles that are too small to see
- These particles are arranged differently in solids, liquids, and gases
- Explains how matter behaves using the idea of particles, which are tiny portions of matter
Hypothesis and Theories
- Hypothesis is a suggestion for an explanation of observed phenomena
- A theory is formed when a hypothesis has been tested and widely accepted as valid
Other
- Matter can only flow if the particles can move past one another
- Matter can only change volume if the particles can spread out or move closer together
- A space where there are no particles at all is called a vacuum, which contains nothing
