Everything I Should Know
20 questions per run ā¢ pulled from a 150-question bank ā¢ Score shows only at the end
1) Pressure Conversions (Dimensional Analysis)
Goal: build a conversion factor that cancels the given unit and leaves the target unit.
- Write the given as a fraction: given Ć (factor)
- Put the given unit in the denominator (or numerator) so it cancels.
- Example idea: if converting kPa ā Pa, use 1000 Pa / 1 kPa.
Tip: set your answer unit first, then choose a factor where the given unit appears on the opposite side so it cancels.
2) Charlesās Law Formula + Temperature Rule
Use Charlesās Law when pressure stays constant:
V1 / T1 = V2 / T2
- Kelvin only: K = Ā°C + 273
- If solving for V2: V2 = V1 Ć (T2/T1) (T in Kelvin)
- If solving for T2: T2 = T1 Ć (V2/V1) (answer in Kelvin)
Quick check: if temperature goes up, volume should go up (same gas, same pressure).
3) Theoretical vs Experimental (How to think)
- Theoretical = what the math predicts (ideal/expected).
- Experimental = what you measured (real data).
- When you miss a question, check units + rounding + whether you used K instead of Ā°C.
Tip
Use your notes and look for key vocabulary in your Science Notebook (diffusion, gradient, equilibrium, hemoglobin, pressure units, etc.).
You will answer 20 questions. Each run includes: 2 pressure conversion input questions + 2 Charlesās Law input questions + 16 multiple choice.
Heavier focus each run: Diffusion & Concentration Gradients, Iron (Fe) & Nutrition, and Gases & Pressure.
