Question

19 multiple choice 1 point what phase change is involved when a solid turns into a gas freezing melting ionization deionization vaporization/evaporation sublimation deposition condensation clear my selection

Explanation:

To solve this, we analyze each option:

• Freezing: Liquid to solid. Eliminate.
• Melting: Solid to liquid. Eliminate.
• Ionization/Deionization: Not phase changes of states (involve ions). Eliminate.
• Vaporization/Evaporation: Liquid to gas. Eliminate.
• Sublimation: Solid directly to gas. This matches.
• Deposition: Gas to solid. Eliminate.
• Condensation: Gas to liquid. Eliminate.

Answer:

Sublimation (the option corresponding to "Sublimation")
