Final answer:
The energy interaction model of water at 0 degrees involves phase change, where heat is absorbed or released as the water changes from solid ice to liquid water and then to steam vapor. At 0°C, the ice melts and absorbs heat, while at 100°C, the water boils and absorbs more heat.
Step-by-step explanation:
The energy interaction model of water at 0 degrees can be described using the concept of phase change. When heat is added to a sample of ice at -20°C, the temperature of the ice rises linearly until it reaches 0°C. At this temperature, the ice begins to melt, absorbing a specific amount of heat. Once all the ice has melted, the temperature of the liquid water rises at a new constant rate. At 100°C, the water starts to boil, and the temperature remains constant while the water absorbs a significant amount of heat during this phase change.
