Cambios físicos: ¿qué es un cambio físico?

The video tutorial explains the difference between physical and chemical changes in matter. Physical changes involve alterations in appearance or form without changing the composition, such as tearing paper. In contrast, chemical changes result in a new substance, exemplified by burning paper turning into ash. The tutorial highlights that while physical changes may involve changes in size, shape, or appearance, the material's composition remains unchanged. Chemical changes, however, alter the material's composition, resulting in a different type of matter.
