ChemistryEasysingle choice

Dry ice ( $C O_{2}$ solid) sublimes slowly in an open dish at its sublimation temperature, taking heat from the air around it. Choose the correct statement.

Options:

Answer:

Solution:

Sublimation absorbs heat, so $q_{re v} > 0$ for the system and $Δ S_{sys} > 0$ (solid to gas).

The air loses that heat, so $Δ S_{s u rr} < 0$ . Answer: (A).
