Frost forms when water vapor changes directly to
ice in a process called deposition. If you were to
model the water particles before and after
deposition, how would they compare?
A. Before deposition, the particles vibrate in
place; after deposition, they slide by each
other.
B. Before deposition, the particles slide by each
other; after deposition, they vibrate in place.
C. Before deposition, the particles vibrate in
place; after deposition, they move quickly in
all directions.
D. Before deposition, the particles move quickly
in all directions; after deposition, they vibrate
in place.
