Reference no: EM13891721

A calorimeter contains 50 g of water at 50°C. The temperature falls to 45°C in 10 minutes. When the calorimeter contains 100g of water at 50°C, it takes 18 minutes for the temperatureto become 45°C. Find the water equivalent mass of the calorimeter. (Specific heatof water C = 4190 J/Kg.K).
