Step-by-step 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. 
- it is easily reversible
 - leads to the production of no new kinds of matter
 - involves no change in mass
 - requires little energy
 
Therefore, some of the examples of physical changes are: 
- boiling 
 - melting 
 - freezing 
 - condensation
 - sublimation
 - magnetization of metals 
 - breaking of glass
 - cutting of wood
