List the FOUR examples of physical changes shown in the video. Why are these physical changes?

Explanation:

A physical change is a change that alters the physical properties of matter most especially the state and the form. This change has the following attributes.

Therefore, some of the examples of physical changes are:

if two electrons have the same n, the same ℓ, and the same ml, then they are in the same orbital. the pauli exclusion principle states that no two identical fermions (a fancy word for electrons and other subatomic particles like electrons) may occupy the same quantum state in an atom simultaneously.
