To find the total heat energy released when 5.0 g of water at 20°C changes into ice at 0°C, we need to consider two steps in the process: 1. Cooling the water from 20°C to 0°C. 2. Changing the water at 0°C to ice at 0°C. ### Step 1: Calculate the heat released while cooling the water from 20°C to 0°C The formula to calculate the heat released when cooling is given by: ...
