Study Notes
Definition of Matter
- Matter is anything that has mass and occupies space
- Examples of matter include air, water, rocks, and people
Composition of Matter
- Matter is composed of atoms
- Atoms are the building blocks of all matter
- Different combinations of atoms make up all the matter we see around us
States of Matter
- There are four states of matter: gas, liquid, solid, and plasma
- Each state has a distinct form of matter
- States of matter are determined by the arrangement and movement of particles and the strength of intermolecular and atomic forces
Characteristics of States of Matter
- Gas: very compressible, low density, can flow
- Liquid: moderately compressible, high density, can flow
- Solid: not compressible, high density, cannot flow
- Plasma: high-energy state, formed at very high temperatures or when subjected to a strong electric field
Changes of State
- Energy can change matter into different states
- Solids become liquids or gases when heated
- Gases can transform into plasma at very high temperatures or when subjected to a strong electric field
Special States of Matter
- Liquid crystal: a state that exists within a certain temperature range, has properties of both liquids and solids
- Bose-Einstein Condensates (BEC): a state of matter in which separate atoms are cooled to temperatures very close to absolute zero
Macroscopic Properties of Matter
- Macroscopic properties can be visualized by the naked eye and measured easily
- Examples of macroscopic properties include density, fluidity, and compressibility
Classification of Matter
- Matter can be classified into two categories: pure substance and mixture
- Pure substance: element or compound
- Mixture: homogeneous or heterogeneous, with examples including colloid and suspension
Physical and Chemical Properties
- Matter can be described with both physical properties (e.g. density, fluidity) and chemical properties
- Physical techniques can change the physical properties of matter, but the chemical composition remains the same
