Study Notes
States of Matter
- Matter can exist in three states: solid, liquid, and gas.
- The states of matter are classified by their ability to change shape and volume.
- All matter is made up of tiny, moving particles.
- For any given substance, its solid, liquid, and gas forms are made up of the same kinds of particles.
- The particles that make up matter also have kinetic energy— the energy of motion.
- In all states of matter, even solids, the particles are in constant motion.
- The motion of particles increases, their kinetic energy also increases.
- In solids, particles are in contact with each other in a structured pattern, and they vibrate in place without changing their places in the structure.
- In liquids, particles are able to move past each other but still maintain contact.
Particle Arrangement and Movement
- Gas particles are far apart and move quickly, collisions are rare
- Liquid particles have less kinetic energy than gas particles, so attraction between particles is more influential
- Solid particles have the least kinetic energy and are held close together. Attraction between particles has the most influence so they can only vibrate
Water's Unique Properties
- Water's solid form (ice) has a different arrangement of particles than liquid water
- Ice is less dense than liquid water because the spacing between molecules is greater
- This is why ice floats on water
Importance in the Earth System
- Large bodies of floating ice are crucial for animals like penguins and walruses
- The ice habitats allow these animals reach food and rest
