Study Notes
Branches of Chemistry
- Biochemistry is the study of chemical processes in living things.
- Inorganic Chemistry deals with the study of inorganic compounds.
- Organic Chemistry is the study of carbon-containing compounds.
- Physical Chemistry is the study of the physical properties and behavior of matter.
- There is no "Electrical Chemistry" branch.
The Scientific Method
- The scientific method is a systematic process used to develop and test scientific knowledge.
- It involves making observations, forming hypotheses, and testing these hypotheses through experimentation and data analysis.
Classification of Matter
- Matter can be classified into pure substances (elements and compounds) and mixtures.
- Elements are substances that consist of only one type of atom.
- Compounds are formed when two or more different elements combine in a fixed ratio.
- Mixtures are physical blends of two or more substances.
Units and Instruments of Measurement
- Units of measurement are standard amounts used to express physical quantities.
- Instruments of measurement are used to measure physical quantities with precision and accuracy.
- Examples of units of measurement include grams, liters, and meters.
Chemistry for Engineers
- Chemistry is essential for engineers as it provides a fundamental understanding of the properties and behavior of materials.
- This understanding is crucial for designing and developing new materials, processes, and systems.
