during which change of state would the volume of a substance increase the most?\n deposition\n melting\n…

Brief Explanations:

Deposition is gas - to - solid, volume decreases. Melting is solid - to - liquid, volume change is relatively small. Vaporization is liquid - to - gas, large volume increase. Sublimation is solid - to - gas, also large volume increase. But sublimation skips the liquid state and generally has a more significant volume increase as it goes directly from a more compact solid state to a highly dispersed gas state.

Answer:

sublimation
