🏁 Kinetic Theory of Gases – Stage 3 (Page 10)

Final Mixed Test + One-Page Capsule + Exam-Day Strategy

🧪 Final Mixed Test (IIT Level)

Q1. If temperature of a gas is doubled, RMS speed becomes:

  • A) 2 times
  • B) √2 times
  • C) 4 times
  • D) No change

Answer: B

Q2. Pressure of gas depends on:

  • A) Mass of molecule
  • B) Shape of container
  • C) Average kinetic energy
  • D) Nature of gas

Answer: C

Q3. At same temperature, which gas has maximum RMS speed?

  • A) H₂
  • B) O₂
  • C) N₂
  • D) CO₂

Answer: A

📌 One-Page Formula Capsule

  • ⟨KE⟩ = (3/2) kT
  • vrms = √(3RT / M)
  • v̄ = √(8RT / πM)
  • vmp = √(2RT / M)
  • P = (1/3) ρ vrms2
  • P = nkT

📊 Speed Relations (Must Remember)

vrms > v̄ > vmp

v ∝ √T   |   v ∝ 1 / √M

⚠️ Ultimate IIT Mistakes to Avoid

  • Using linear T instead of √T
  • Mixing RMS, average & most probable speeds
  • Thinking pressure depends on mass
  • Wrong graph slope interpretation

🧠 Exam-Day Strategy (KTG)

  • KTG questions are FAST → attempt early
  • Use proportionality instead of full calculation
  • Graphs = easy marks (don’t skip)
  • Assertion–Reason mostly conceptual

🏆 Rank Booster Checklist

  • ✔ All formulas memorized
  • ✔ Graphs understood
  • ✔ Numerical shortcuts practiced
  • ✔ Concepts crystal clear
