Heating Curve
 

Heating Curve

  1. The temperature of the solid rises as we increase the energy of the particles.
  2. At the melting point, the temperature stops rising and the line becomes horizontal.
  3. The solid continues to melt. The energy we put in is weakening or breaking the forces of attraction between the particles, allowing the substance to change from a solid to a liquid. The energy is called the latent heat. There is a change of state but no change of temperature.
  4. When all the solid has melted, the temperature of the liquid will rise again.
  5. At the boiling point, the temperature stops rising again and the line becomes horizontal.
  6. When all of the liquid has boiled, the temperature of the gas will rise again.
