Study Notes
States of Matter
- Matter exists in five states: solid, liquid, gas, plasma, and Bose-Einstein condensate
- Matter is anything that has mass and occupies space. It can be living or non-living.
- Matter can be detected using the senses. It makes up everything in the world.
- Scientists now study four states, including plasma and Bose-Einstein condensate, in addition to the familiar three.
Particle Theory of Matter
- Matter is made of tiny particles.
- These particles are in constant motion and are held together by attractive forces.
- The movement of these particles (and the amount of space between them) depends on the amount of energy they possess.
Solid State
- Solids have a definite shape and volume.
- Particles in solids are tightly packed and arranged in a regular pattern.
- This tight arrangement makes solids incompressible.
- Solids have the lowest kinetic energy.
- Solids contain more matter per unit volume, yielding high density.
- Examples include a cup, shirt, book, eraser.
Liquid State
- Liquids have a definite volume, but they take the shape of their container.
- Particles in liquids are loosely packed and can move and slide past each other.
- Liquids can assume the shape of their container.
- Liquid particles have higher kinetic energy than those in solids.
- Examples include maple syrup, shampoo, olive oil, orange juice.
Gaseous State
- Gases have no definite volume and take the shape of their container.
- Particles in a gas are widely separated.
- Gas particles have the highest kinetic energy.
- Gases readily fill all available space.
- Gases are compressible.
- Examples include helium in a balloon, steam from a kettle, argon in a tank, nitrogen in a tank.
Plasma State
- Plasma has no definite volume or shape.
- Plasma contains charged particles that are widely separated.
Bose-Einstein Condensate
- A Bose-Einstein condensate is a state of matter where separate atoms or subatomic particles, cooled to near absolute zero, coalesce.
- These particles act as if they were one single atom, on a macroscopic scale.
- Examples include lasers, neutron stars, and quantum computers.
Changes in Matter
- Matter can change from one phase to another when conditions change, mostly temperature.
- Rising temperature increases particle kinetic energy, causing matter to change state into more active ones.
- Lowering temperatures decreases the energy of the particles, leading to them being attracted to each other, potentially changing states.
Physical Changes
- In physical changes, the substance's composition is not altered.
- Common physical changes include transitions between solid, liquid, and gas (e.g., melting, freezing, evaporation, condensation, sublimation, deposition).
Chemical Changes
- In chemical changes, the chemical composition of the substance is altered, resulting in a new substance.
- Examples include rotting fruit, cooking an egg, burning wood, rusting metal, and baking a cake.
- Evidences of a chemical change include a change in colour, odor, or taste, and/or the release of gas.
