Question

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.

Answer 1

Freezing would go to a solid formation and Melting would go to a liquid formation

Answer 2

Melting is an endothermic reaction, while freezing is an exothermic reaction.

Step-by-step explanation:

The melting process requires energy, making it endothermic.

The diagram for this would be roughly similar to _/⁻⁻ with the / part representing the melting process, and the ⁻⁻ part equivalent to liquid.

The freezing process releases energy, making it exothermic.

The diagram from this process is roughly similar to ⁻⁻\_ with the \ part representing the freezing process and the _ part equivalent to frozen.
