XPERIMENT2* POST LAB E 1. Why does the heating curve for ice/water/steam have areas which are flan? 2. If 64.8 grams of ice at 0 °C is heated until it has all been converted to steam at 100 C, how many calories are needed? What is this energy expressed in Joules? 3. Assuming that no heat is lost, what will the final temperature be when a 15.0 g piece of silicon at 95.0 °C is placed in 50.0 g of water at 20.0 °C? The specific heat capacity of silicon is 0.169 cal/g c Metal A has a specific heat capacity of 0.215 cal/goC and Metal B has a specific heat capacity of 0.0382 cal/g C. Which of these will cause a greater increase in the temperature of the cold water in a calorimeter? Explain your answer 4.
