Question

during which change of state would the volume of a substance increase the most?
○ deposition
○ melting
○ vaporization
○ sublimation

Explanation:

To determine which change of state increases volume the most, we analyze each process:

• Deposition: Gas → Solid (volume decreases).
• Melting: Solid → Liquid (volume increases slightly, as particles move from a rigid to a more mobile state but still closely packed).
• Vaporization: Liquid → Gas (volume increases, but starts from a liquid state).
• Sublimation: Solid → Gas (skips the liquid state). Solids have closely packed particles, and gases have particles far apart with large empty spaces. Sublimation transforms a highly compact state (solid) directly to a highly expanded state (gas), resulting in a larger volume increase than vaporization (which starts from a less - compact liquid) or melting (small increase).

Answer:

D. sublimation
