What does the flat part of a heating curve indicate?

What does the flat part of a heating curve indicate? Heating curves show how the temperature changes as a substance is heated up. Cooling curves are the opposite. They show how the temperature changes as a substance is cooled down. Just like heating curves, cooling curves have horizontal flat parts where the state changes from […]
