3rd Form C

Notes

3rd Form Chemistry Study Guide – Exam Review 1. States and Changes of Matter • Key Concepts: Solid, liquid, gas; evaporation, boiling, diffusion, osmosis. Study Tip: Know how to identify these processes in real-life scenarios. 2. Heating Curves and Kinetic Energy • Understand the phases in a heating curve: o Know the process occurring in each segment. Eg melting, freezing, boiling o Relate segments to kinetic energy 3. Separation Techniques • Know methods for separating mixtures: o Filtration: Sand and water o Distillation: Alcohol and water o Crystallization: Sucrose from sugarcane o Separating funnel: Oil and water • Types of Mixtures: Homogeneous and heterogeneous. 4. Solubility and Solubility Curves • Key Terms: o Saturated: Max amount dissolved o Unsaturated: More can dissolve o Supersaturated: Too much dissolved—precipitation may occur • Use solubility graphs to interpret how temperature affects solubility. 5. Solutions and Mixtures • Solute: Substance being dissolved • Solvent: Substance doing the dissolving • Solution: Uniform mixture o Types: Suspension: Particles settle (e.g. sand in water) Colloid: Cloudy, doesn't settle (e.g. fog, lotion) 6. Atomic Structure • Know how ...
