  4. Physical or Chemical Change?

  5. A Closer Look: Chemical Vs. Physical Change Physical change: • Material is the same before and after the change • The change can be “undone.” For example: Ice melting

  6. A Closer Look: Chemical Vs. Physical Change • Chemical change: • The substance @ the beginning is not @ the end • New substances are formed • The change cannot be • “undone." For example: Nail rusting

  7. A Closer Look: Chemical Vs. Physical Change

  8. Solutions • Solution- a mixture of 2 substances • Solute- the substance being dissolved; lesser in amount • Solvent- the liquid that does the dissolving; larger in amount • Solutes & Solvents may be in any state: solid, liquid or gas

  9. TypesofSolutions Heat affects Solubility The hotter the liquid the more Solute it can hold.
