What are Physical Apperances/Changes?
Physical appearances are what matter looks like or feels like. That can be a color, size, or texture. Physical changes are any change in physical properties. Some physical properties are size, shape, color, and texture. Physical Changes do NOT form a new substance. The substance stays the same, but it changes some of its physical properties. Sometimes, physical changes can be reversed like when you tape a piece of ripped paper together. Some examples of Physical changes are ripping paper, painting a wall blue, breaking glass, and cutting wood. Physical changes can be reversed, but only sometimes. An example of this is folding paper. When you fold it, you can reverse that fold and get the original shape and size of the paper back.
