Question

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

Explanation:

To determine the phase change when a gas turns into plasma, we analyze each option:

• Condensation: Gas to liquid, incorrect.
• Ionization: Process where gas (with atoms/molecules) gains enough energy to ionize (form ions and free electrons), forming plasma. This matches gas to plasma.
• Vaporization/Evaporation: Liquid to gas, incorrect.
• Deposition: Gas to solid, incorrect.
• Sublimation: Solid to gas, incorrect.
• Deionization: Plasma to gas (reverse of ionization), incorrect.
• Melting: Solid to liquid, incorrect.
• Freezing: Liquid to solid, incorrect.

Answer:

B. Ionization
