  1. States of Matter; liquids

  2. A liquid is defined as matter that has a definitevolumeBUT has nodefiniteshape. Moleculesare always moving… fluidity. There are two elementsthat are liquids at room temperature (25°C/ 77°F);MERCURY&BROMINE Liquids

  3. MERCURY Mercury Liquids BROMINE Bromine reaction

  4. But, as you heatthings up… fourmore elements become liquid. For temperatures up to 40°C (104°F) Francium, Cesium, Gallium, & Rubidiumwill become liquids. Notice that Bromine is the ONLY nonmetalthat is in the liquid state. Liquids

  5. Francium Liquids Cesium Gallium Rubidium

  6. There are other types of liquids too. (that are not elements) water(H2O) rubbing alcohol (C3H7OH) These are pureliquids that have their own individualproperties. Liquids

  7. BUT, most things are mixed. When you put things together, that don’t mix, they call that aheterogeneousmixture. These arechunky mixtures and may separate out over time. One example is muddy water. liquids

  8. BUT, when you mixthings together, and they stay together, it is called aSOLUTION. Solutions are homogeneousmixtureswhich aresmooth, uniform throughout. Once mixed, the components will stay mixed. One example is salt water. liquids

  9. There are threetypes of solutions unsaturatedsolution – more stuff can be still be mixed in the solution solutions saturatedsolution – the perfect amount of stuff is in the solution supersaturatedsolution – extra stuff was mixed in the solution super demo

  10. Examples of solutions are koolaid- mixture of flavoring, sugar, & water soda- mixture of flavoring, sugar, carbonated water, & acid bubbles- mixture of glycerin, soap, & water windex- mixture of ammonia, water, fragrances, etc. solutions

  11. Tell Mrs. Hatters your idea for your element project. Any incomplete assignments? What should you do now?
