To help you ace the General Science section, here is a comprehensive breakdown of the essential chemistry topics you need to master. 1. Matter and Its States
Latent Heat: Heat required to change the state without changing temperature. 2. Atomic Structure Understanding the building blocks of matter is crucial. Proton (discovered by Ernest Rutherford/Goldstein). Electron (J.J. Thomson). Neutron (James Chadwick). Atomic Terms: Atomic Number (Z): Number of protons. Mass Number (A): Protons + Neutrons. chemistry notes ssc

Natural Acids: Citric acid (lemons), Acetic acid (vinegar), Formic acid (ant stings). Bitter taste, turn red litmus blue, pH > 7. Electron (J
The fourth state of matter (found in stars/fluorescent bulbs). Bose-Einstein Condensate: The fifth state of matter. Key Processes: Sublimation: Solid to Gas (e.g., Camphor, Dry Ice). Deposition: Gas to Solid.
