Matter and its Classification
- Matter is anything that has mass and takes up space.
- Matter can be classified physically as solids, liquids, or gases.
- Solids have a definite shape and volume.
- Liquids have a definite volume but take the shape of their container.
- Gases have no definite shape or volume.
- Matter can be chemically classified as metals and nonmetals.
- Metals are elements that can lose electrons.
- Nonmetals gain electrons.
Molecular Structure
- Molecules are small particles that exist independently.
- They can consist of the same type of atom (homoatomic) or different types (heteroatomic).
- Examples of molecules include: H2, O2, H2O, Fe2, CO2, SO2, and H2O.
Properties of Matter
- There are two types of properties: physical and chemical.
- Physical properties can be observed without changing the substance's identity (e.g., mass, density, boiling point, melting point).
- Chemical properties describe how a substance reacts with others, leading to changes in composition or structure.
Physical Quantities
- Physical quantities are measurable properties like size or density.
- Derived quantities are calculated using other physical quantities.
- The international system (SI) and British systems are used for measurement.
- Key physical quantities include length, mass, time, and electric charge.
Applications of Chemistry
- Chemistry plays a crucial role in various industries, including communication, energy production, and manufacturing.
- Specific examples include:
- TNT explosives
- Nitroglycerine
- Dynamite
- Hydroxides
