Some Basic Concepts of Chemistry

  • Change of state
    • A change of state occurs because heat energy breaks the force of attraction between particles. Kinetic energy of the particle increases.
  • Melting point
    • The temperature at which a solid melts into a liquid at normal atmospheric pressure.
    • At melting point, the temperature does not change until all solid converts into liquid.
  • Latent heat
    • The heat required to break the force of attraction between the particles at transition temperature. This heat becomes confined within the material and is cal…
