Question

One day in the chemistry lab students put a few pieces of dry ice into a beaker. (Dry ice is solid, frozen carbon dioxide.) They see vapor rising from the dry ice, but no liquid, as it slowly disappears into the air at room temperature. What kind of phase transition did the students observe?Question 11 options:A) MeltingB) DepositionC) EvaporationD) Sublimation

Answer 1

`D\text{ : Sublimation}`

Step-by-step explanation:

Here, we want to get the kind of phase transition that occurred

From the information given, we have a transition from the solid state to the vapor state. However, an important point stood out. There was no liquid phase in the transition

This kind of phase change is what we know as sublimation

It is the direct change of state from the solid to the vapor state of some substances. Other substances capable of this include iodine, naphthalene etc
