What changes of state would involve water absorbing energy?
From water at solid state or ice change to liquid the process is called melting. From water as solid to gas the process is called sublimation. From water as liquid to gas the process is called evaporation. All these 3 processes involve change of state and absorb heat.
Does a change in position always involve a force?
Yes, a change in position always involve force.
What is true about oxidation-reduction reactions?
They involve either transfer of electrons, or a change in the oxidation state of some atoms involved.
