Are latent heats denoted by delta H? If so, does this mean latent heats equate to change in enthalpy?

Latent heats are usually denoted and usually come about due to phase changes. It's more appropriate to say something like:
Edit: Apparently L is usually specific (i.e. per unit mass) latent heats.
Further edit: When you go through a phase transition, you break bonds (enthalpy change) and change the freedom of the atoms/molecules involved (entropy change).Last edited by Kyle_S-C; 13-02-2010 at 04:27.

Isnt Latent heats just the capital L? They are slightly different as Latent heat is when a substance changes state where as a change in enthalpy can be for any reaction, unless its the same substance but a different state for instance melting ice then I dont believe latent heat should equate to the enthalpy change.
