Presentation Transcript

  1. Matter and Its Changes

  2. Matter- anything that has mass and takes up space • Physical Change- physical properties change, but the identity of the substance does not change

  3. EXAMPLES OF PHYSICAL CHANGES FREEZING WATER MELTING ICE

  4. PhysicalProperty-any characteristic of a material that can be observed or measured without changing the identity of the material

  5. Density-the amount of mass a material has in a given volume (Density=mass/volume) • Melting Point-the temperature at which a solid becomes a liquid

  6. Freezing Point-the temperature at which a liquid becomes a solid • Specific Heat-the amount of heat needed (measured in Joules) to raise the temperature of 1Kg of substance 1 degree Celsius. (J/kg*C) • Solubility- tells you how much of a solute will dissolve at a given temperature

  7. States of matter- there are four states of matter: solid, liquid, gas, and plasma; the state of matter depends on its temperature and pressure

  8. Chemical Change- a change in the identity of a substance due to the chemical properties of that substance (Is it reversible?)

  9. EXAMPLES OF CHEMICAL CHANGES • RUST • LIGHTING A MATCH

  10. Chemical Property- any characteristic that gives a substance the ability to undergo a change that results in a new substance

  11. Law of conservation of mass- the mass of what you end with is always the same as the mass of what you start with
