Freezing and Melting are two different physical changes that involve the same amount of energy. compare and contrast the potential energy diagrams that would represent each of these processes. Be specific in your comparison.

Another discussion question.I shall be happy to critique your work.
Can you answer it please? I just want to compare my answer..
So I do all the typing and thinking while you compare. That takes up my time so I can't answer other questions. It's better for you to do all the typing and thinking and let me compare. Much more efficient process.
Freezing and melting are two different physical changes that involve the same amount of energy. In an exothermic reaction, the amount of energy in the reactants is higher than the resulting amount of energy in the products. This means that the line graph starts at a higher energy value (representing the potential energy of the reactants (melting)) and ends at a lower energy value (representing the potential energy of the products(freezing)).
In freezing, the stronger attraction that results in closer/shorter bonds (though the overall density increase due to the highly ordered structure) than in melting water so the potential energy is lower.
please check my answer
Wait wait, nevermind, check this one:
In freezing, the amount of energy in the reactants is lower than the resulting amount of energy in the products. This means that the line graph starts at a lower energy value (representing the potential energy of the reactants) and ends at a higher energy value (representing the potential energy of the products).
In melting, the amount of energy in the reactants is higher than the resulting amount of energy in the products. This means that the line graph starts at a higher energy value (representing the potential energy of the reactants) and ends at a lower energy value (representing the potential energy of the products).
