Study Notes

Chemistry Vocabulary Study Notes

Matter: Anything that has mass and occupies space, fundamental to understanding chemical concepts.
Chemistry: The branch of science focused on the composition, structure, properties, and changes of matter.
Organic Chemistry: Specializes in studying compounds that contain carbon, integral in pharmaceuticals and biological applications.
Inorganic Chemistry: Focuses on substances generally lacking carbon, including metals, minerals, and organometallic compounds.
Biochemistry: Examines the chemical processes and substances occurring within living organisms, bridging biology and chemistry.
Analytical Chemistry: Concerned with the composition of materials, using techniques to determine quantitative and qualitative properties.
Physical Chemistry: Investigates the physical principles underlying chemical interactions, including energy transfer and reaction mechanisms.
Pure Chemistry: Engages in the pursuit of chemical knowledge purely for intellectual curiosity, without immediate practical application.
Applied Chemistry: Directs research towards practical goals, often used to solve specific problems or develop new technologies.
Technology: Refers to the tools and methods developed by society to fulfill needs and desires, closely linked to advancements in chemistry.
Macroscopic: Refers to objects or phenomena large enough to observe without aid; critical for initial chemical observations and experiments.
Microscopic: Describes entities that require magnification to view, essential for understanding molecular structures and reactions.
Biotechnology: Integrates scientific principles with biological processes to create products and technologies that improve quality of life.
Pollutant: Harmful materials present in the environment (air, water, soil) that pose risks to health and ecosystems.
Scientific Method: Systematic approach for investigating phenomena, involving observation, hypothesis formulation, experimentation, and theory development.
Observation: Involves gathering data using the senses, often requiring measurements for accuracy and reproducibility in scientific inquiry.
Hypothesis: A tentative explanation proposed for observations, forming a basis for further investigation and experimentation.
Experiment: A structured procedure designed to test a hypothesis; must be repeatable to validate findings.
Manipulated Variable: The independent variable in an experiment that is altered to observe its effects on the responding variable.
Responding Variable: The dependent variable that is measured and observed in response to changes made in the manipulated variable.
Theory: A well-supported explanation that encompasses a broad range of observations, gained through extensive experimental evidence.
Scientific Law: A concise statement summarizing consistent results from multiple observations and experiments, often expressed mathematically.
