When determining the heat capacity of a coffee cup calorimeter, Sammy uses the same volumes and temperatures of water as Sally (see Figure 1). However, instead of starting with the cool water in the calorimeter, he starts with the warm water in the calorimeter. They get in an argument- Sammy declares that their measured final temperatures will be the same because they are using the same volumes and temperatures of water. Sally disagrees. Who is correct? Explain your answer. Sammy: 50.0 mL, Temp = 20°C Sally: 50.0mL, Temp = 45°C Sammy: 50.0 mL, Temp = 45°C Sally: 50.0 mL, Temp = 20°C Figure 1: Sammy and Sally's experiments.
