I'm going crazy! The heat necessary to change the state of water between a solid and a liquid is called the latent heat of vaporization, latent heat of solidification, latent heat of fusion, latent heat of liquefaction, or none of the above. I thought it was none of the above, but now I think it might be latent heat of fusion. Pleaz help. Thanks

You are right, it is the latent heat of fusion.

Thank you very much. I am always second guessing myself

the latent heat of fusion

Don't second guess yourself.

No problem! It's always good to double-check and make sure you have the correct answer. In this case, the heat necessary to change the state of water between a solid and a liquid is indeed called the latent heat of fusion. This is because during this phase change, the water absorbs heat energy in order to overcome the intermolecular forces holding the water molecules in a fixed, solid arrangement. Once enough heat is added, the water molecules break free from these forces and transition into the liquid state. So, the correct answer to your question is indeed the latent heat of fusion.
