When does carbon dioxide absorb the most heat energy? uring freezing during deposition during sublimation during condensation?

The answer for the given question above would be the third option. Carbon dioxide absorbs the most heat energy during SUBLIMATION. By definition, sublimation is the transition of a substance from the solid to the gas phase without passing through the intermediate liquid phase. Hope this answers your question.

Answer;

-During sublimation

Explanation;

-Carbon dioxide in its solid form is known as “dry ice,” because under common conditions it sublimates, turning directly into gas, rather than melting into liquid.

-The enthalpy of sublimation, or heat of sublimation, is the heat required to change one mole of a substance from solid state to gaseous state at a given combination of temperature and pressure,

-The low temperature and direct sublimation to a gas makes dry ice an effective coolant, since it is colder than water ice and leaves no residue as it changes state. Its enthalpy of sublimation is 571 kJ/kg
