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

One current education question and answer requested students to tell what they consider is the most important important concern for a student to do if they wanted to hit success. The one that response stood out from the rest was practice. People who definitely successful do not become successful by being born. They work hard and dedication their lives to succeeding. If you tend to reach your goals, keep this in mind! down below are one of the answer and question example that you can potentially utilise to practice and elevate your understanding and also give you insights that will help you to preserve your study in school.

Question:

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

Answer:

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

They could possibly hopefully guide the student answer the question by make use of the questions and answer examples. Then can certainly have some sharing in a group discussion and also learning with the classmate with reference to the topic, so another student also attain some enlightenment and still keeps up the school learning.
