On a warm afternoon (26°C), James is making fruit punch while the ice is melting (0°C) in a bowl. Assume that the specific heat capacity of the punch is 2.7 x 103 J kg-1°C-1 and of water is 4.2 x 103 J kg-1°C-1. The latent heat of fusion of water is 3.34 x 105 J kg-1. I. Michelle, a friend of James, likes her punch served ice cold, at O°C. What is the minimum mass ice cube she should select to cool her 60-gram punch from 26°C to 0°C? II. James prefers his 60-gram punch served at little warmer. What temperature will the drink be if he places a 6 g ice cube into his punch? III. Sanya, another friend, decides she wants a cup of tea.
