Georgia Standards: Physical and Chemical Changes

Front

When water freezes into ice, what type of change does it undergo?

Back

It undergoes a change in the form or appearance of the substance without changing its chemical composition.

Front

When Jackson bakes a cake, what kind of change is happening to the ingredients?

Back

The change involves the rearrangement of atoms in the ingredients to form a new substance with different properties.
