Cambios físicos: video de evaluación

The video tutorial covers different types of changes and states of matter. It begins with physical changes, using tearing paper as an example, and then moves to chemical changes, illustrated by burning paper. The tutorial also discusses the states of matter, focusing on ice as a solid, and explains the processes of melting and evaporation, where ice turns into liquid and liquid transforms into gas, respectively.
