Question

Which change of state is shown in the model?

condensation
evaporation
sublimation
deposition

Answer 1

I can’t see the model image. Could you upload it or describe what you see (arrows, particles, droplets, ice, steam, etc.)?

Quick ID tips:
- Condensation: gas → liquid (steam or vapor forming droplets or a liquid film).
- Evaporation: liquid → gas (liquid losing molecules to form vapor; often shown with arrows leaving a liquid surface).
- Sublimation: solid → gas (solid disappears directly to vapor, e.g., dry ice).
- Deposition: gas → solid (vapor turning directly into frost or ice crystals).

If the model shows vapor turning into droplets or a liquid layer, the answer is condensation. If you describe it I’ll pick the correct choice.
