Chilling Water Problem, States of Matter and Intermolecular Forces, Chemistry

Sal continues this short series on specific heat and vaporization. The situation he poses uses 500 grams of liquid water at 60 degrees Celsius to get the water to zero degrees Celsius. The ice he adds to the water comes out at -10 degrees Celsius. The question is: how much ice is needed to cool the sample of water down to zero degrees Celsius? The rest of the video covers the calculations required to arrive at the answer.
