NCERT chapter connection · Learning goals & preparation

By the end, you can…

  • Explain Passes when particle size < pore opening
  • Change one input at a time and predict its effect before checking the model.
  • Apply the relationship in a quiz and explain the reasoning behind your answer.

Useful preparation: Counting particles, ratios and the difference between a model and a real substance. Suggested previous stop: Investigate a charged beam.
