📖 The Temperature That Refuses to Rise
Heat an ice cube. Its temperature rises steadily toward 0°C. Then something strange happens — you keep adding heat, but the temperature STUBBORNLY STAYS at 0°C until ALL the ice has melted. Why? Because the energy isn't making particles move faster (which would raise temperature). Instead, it's being used to break the bonds holding particles in fixed positions. Only when all bonds are broken does the temperature start rising again. Same thing happens at 100°C when water boils!
