Drawing assignment about phases changing, chemistry homework help

Anonymous

Question Description

All the observable changes you see when matter changes phase—the bubbles during boiling, the crystallization during freezing, and the “disappearing” of matter during evaporation—can can be explained at the particle level. Use your understanding of kinetic molecular theory and phase changes to complete the following assignment.

Use paper, pencil, and a scanner to create particle-level diagrams showing the particle’s relationship to other particles according to the phase they are in for two of the following three situations:

bubbles of gas form as pasta water begins to boil on the stove

a refreshing drink contains both ice cubes and water

freeze-drying technology dehydrates foods through sublimation

Clearly label which two situations you are depicting and include a paragraph (three to five sentences long) explanation to accompany each drawing.

attached is my complete answer

First option:
The following particle-level diagram demonstrates the process of bubbles of gas form as pasta
water begins to boil on the stove

As we keep heating the pasta water, the particles increase enough energy to move from the
fluid stage to the vaporous stage. These bubbles are water vapor. When you see water at a
"moving heat up", the bubbles are completely wate...
