the chef melts the ice on the vegetables by leaving it outside in the kitchen in normal temperature, (assuming the kitchen is around 20+ celsius degrees).
it is physical change because only the shape changes, the color and/or odor do not change.

#1. They were used for defense
#2. they were used to kill prey
