1 : apple sliced : the apple was cut into smaller peices : physical change

2 : smashed apple : the apple became a mush : physical change

3 : paper burned : the paper became ash : chemical change

4 : glow stick snapped : the glow stick started glowing : chemical change

5 : apple being burned : the apple became discoloured and turned coal-like : chemical change
