The change from solid to liquid
The change from liquid to gas
The change from gas to plasma.
Explanation:
The changes that are endothermic require energy to be added to the substance.
Changing ice to liquid requires energy be added to break the bonds between the water molecules in a hexagonal crystalline shape.
Changing liquid water to gas requires energy to break the shifting inter molecular forces between the water molecules.
Changing gas to plasma requires a great deal of energy to break the atoms apart, separating the electrons from the neutrons and protons.
