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 0°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. She uses 2000 W mains operated kettle filled with 1.20 kg of water at room tempe

III. Sanya, another friend, decides she wants a cup of tea. She uses 2000 W mains operated kettle filled with 1.20 kg of water at room temperature (26°C). How long will she have to wait for the water to reach boiling point (100°C)?
