What type of change would you expect the heated ice to undergo?
The average kinetic energy of the ice particles is lower.
Energy is transferred from the water into the air.
balls far apart with long arrows between them
a phase change is taking place
slow, mobile, free
a purely physical change because it will change state
Before deposition, the particles move quickly in all directions; after deposition, they vibrate in place.
