Homework Help: Latent Heat of Fusion

  1. Apr 9, 2005 #1
    I have no clue how to do this?

    Which would require more heat, melting 500 g of 0 C ice or turning 500 g of 100 C water into steam?

    You need to know the Latent Heat of Fusion (80 cal/gram) for {Ice → Liquid Water} transition and the Latent Heat of Vaporization (540 cal/gram) for {Liquid Water → Steam} transition. Can you answer the question now??

    I still am not sure what to do...I am taking an online class and we basically have to learn the material ourselves. So if I can get help with just one then I can figure the rest out.
