1. measuring out volumes

   • equipment
     • measuring cylinder for more accurate reading
       • meniscus
         • the tension between the water and the glass
         • meniscus is a bend in the water surface
     • measuring beaker for less accurate quick reading
   • volumes are measured in cm cubed
   • boiling temperature is 100 degrees

2. dissolving

   • definations
     • soluble: a substance that can dissolve
     • insoluble: a substance that cannot dissolve
     • saturated: a solution when no more solute can dissolve
     • solution: a mixture of solute and solvent
     • suspension: a mixture of insoluble solid particles spread through a liquid
