📝 Sample Solutions

Chemistry (Ch.2):
Q: Why does dry HCl gas not change litmus color?
A: Dry HCl doesn’t ionize to form H⁺ ions. Moisture is needed for ionization.

Physics (Ch.6):
Q: Calculate resistance of a 100W, 220V bulb.
A: P=V²/R ⇒ R=220²/100 = 484Ω

Biology (Ch.9):
Q: Draw human digestive system.
Solution: [Diagram PDF] with labeled parts

📌 Subject-Specific Tips

Chemistry: Memorize reactivity series with mnemonics
