Label the enthalpy changes shown in the diagram below. I need help with chemistry please.?

This is the diagram that I need to label (attached). I looked in my chm book to get an idea, but it wasn’t helping. and my professor did not explain this at all.

  • This is quite simple I guess. So ,from solid to gas directly, it is ∆Hosubl, for solid to liquid it is ∆Hofusion, for liquid to gas it is ∆Hovap, for gas to liquid it is -∆Hovap, liquid to solid is -∆Hofusion and gas to solid directly is -∆Hosubl. Hope it helps:)
