Answer

Brief Explanations:

  • For question 12, effusion is defined as the movement of gas particles through a small hole.
  • For question 13, pressure is force applied per unit area.
  • For question 14, solids have particles arranged in a regular pattern.

Answer:

  1. The movement of gas particles through a small hole
  2. Force applied per unit area
  3. Solid
