How much heat is gained or lost when 200 grams of ice melts?

  • Physics -

    you need to first look for the latent heat of fusion (Lf) --- this is a constant, then use the formula:
    Q = m(Lf)
    where Q = heat in Joules, m = mass in grams
    *since it melted, it definitely absorbed/gained heat, thus Q is (+)

    so there,, :)
