WebOct 6, 2024 · Different substances have different melting points and boiling points, but the shapes of their heating curves are very similar. For example, this is the heating curve for iron, a metal that melts at 1538°C and boils at 2861°C. Heating curves show how the temperature changes as a substance is heated up. What is the heating curve diagram? WebJun 24, 2024 · The heating curve is the relationship between the heating system supply temperature and the outside air temperature. Gas molecules have the highest average velocities among the three states of matter so gas has the highest kinetic energy. During freezing, a substance loses a lot of potential energy so solid has the least potential energy. cook head of cabbage
