### Winter Midterm 2013 Q2C

In this problem, my course reader had multiple answers printed and I don't know which is correct.

Is the answer supposed to me more or less ice?

Thanks!!

Hi there! The answer is supposed to be less ice. This can be seen from the $q= mC\Delta T$ equation. Since orange juice has a lower specific heat capacity, less ice will be needed to cool the drink to 16 degrees celsius in comparison to the ice needed to cool the water. Hope that helps!
