Homework Help: Word problem

  1. Sep 17, 2003 #1
    Need help on this word problem please. I don't even know where to start with this one.

    If you convert 3 kg of ice at -30 degrees C into 3 kg of steam at 120 degrees C. Using this as a model can you explain how we make ice-cream with ingredients of 5 degrees C into soft ice-cream at temperature of -5 degrees C using ice at 0 degrees C as the coolant? (remember the salt)

    THANKS.

    It might help if you posted the problem as given.
    Surely it didn't start "If you convert 3 kg of ice at -30 degrees C into 3 kg of steam at 120 degrees C." That's not a sentence!

    If ...... then what??
