Organize these phase changes into the right categories

Groups:

(a) EXOTHERMIC

,

(b) ENDOTHERMIC

• deposition

• sublimation

• melting

• freezing

• condensation

• boiling

Answer explanation

Endothermic means energy is added into the system. This energy is needed for the atoms/ molecules to overcome the attractive forces and allow them to speed up and spread out
