1. A 1.5kg iron horseshoe at 800C is droppes into a bucket of water at 20 C. If the mass of water in the bucket is 5kg, what is the final temperature of the water-iron mixture, given c iron=448 J/kgoC and c water= 4187 J/kgoC? 2. How much ice is needed to cool 150 ml of water from 60oC to 40oC if it is in a copper cup weighing 100g?
