Properties

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


Properties

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

Solutions

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
