Let's make some iced tea!Stir 0.25 kg of ice, initially at - 5oC, into 0.5 kg of tea, initially at 45oC. What is the final temperature?
The specific heat of (liquid) water is cw = 4186 J/(kg Co). The heat of fusion for ice or water is Lf = 3.33 x 105 J/kg. The specific heat of (frozen) ice is ci = 2090 J/(kg Co). Notice that the specific heat is different for ice and water!
