Power question

  1. Oct 30, 2006 #1
    A 2.0 kg bag of ice is used to keep a cooler of pop cold for 5.5 h. If the ice had an initial temperature of -4ºC and, after 5h, was liquid water with a temperature of 3ºC, find the power of energy absorption.

    Any help would be great. I don't know where to start:confused:.

    Write out your givens and your unknown(s). Do you know which formula(e) to use? Is there a chapter in your text you've read over and considered?

    Power = energy / time
