  1. 1. Identifying Chemicals Kelly and Kristina
  2. 2. A physical property is a way to identify a substance using mass, volume, color, hardness and density.
  3. 3. Density <ul><li>Density is a type of physical property of matter.
  4. 4. The formula for density is d=m/v. </li></ul>
  5. 5. Melting and Boiling Point <ul><li>Melting Point is where the temperature at a solid changes to a liquid.
  6. 6. The Melting Point of water is 0 degrees Celsius.
  7. 7. Boiling Point is where the temperature of gas bubbles form in a liquid and rise to the surface and escape a liquid to a gas. </li></ul>
  8. 8. Specific Heat <ul><li>Specific heat of a substance is the amount of heat needed to raise 1 gram of the substance by one degrees.
  9. 9. Different Specific Heats are used to compare how different substances absorb heat. </li></ul>
  10. 10. Solubility <ul><li>Solubility is a measure of how much a substance dissolves into another substance.
  11. 11. An example of solubility is sugar dissolving in water.
  12. 12. Sugar dissolves into water it forms a solution, which is a mixture when the particles are too small to be distinguished from each other and remain constantly and uniformly mixed. </li></ul>
  13. 13. Chemical Property <ul><li>A chemical property is a characteristic that describes how the matter will change under certain conditions. </li></ul>
  14. 14. Reactivity <ul><li>Reactivity describes how likely an element is determined by the number of valence electrons in its atoms. </li></ul>
