It does change its physical look but it does not change chemically.

After a physical change a substance does not change its chemical composition it simply changes its state as, water to ice or vapours.
When matter undergoes a chemical change, the composition of the matter changes. When matter undergoes a physical change, composition of the matter remains the same.
The chemical composition of a substance does not change when it undergoes a physical change.
it means figure it out yourself!
when a pure substance undergoes a chemical change it is no longer that same substance. A chemical change changes the identity of the substance. Hope i helped
Physical change.
A substance that undergoes a physical change is water when it freezes into ice. This process changes the state of the water from liquid to solid without altering its chemical composition. Similarly, when ice melts back into water, it undergoes another physical change. Other examples include the melting of wax or the dissolving of sugar in water.
It does change its physical look but it does not change chemically.
All substances have physical changes.
maybe..
from a solid to gas
