Use a particle model of matter to explain common phenomena involving gases, and phase changes between gas and liquid and between liquid and solid.
- Clarification Statements:
- Examples of common phenomena the model should be able to describe include adding air to expand a balloon, compressing air in a syringe, and evaporating water from a salt water solution.
- Assessment Boundary:
- Atomic-scale mechanisms of evaporation and condensation or defining unseen particles are not expected in state assessment.
