Liquid density Liquid density Presentation Transcript

  • LIQUID DENSITYDecember 13, 2011
  • Your objective Understand what is ‘Density’ Compare the density of liquids through layering
  • DensityDensity is a measure of how closely packed the molecules of a substance are.If the molecules are all packed in close, the liquid is high density.If the molecules have lots of space between them, the liquid is low density
  • You can also compare this to population density to better understand. For this example, think of yourself as a molecule:When it is just the grade 5s in our classroom, there are only 10 students (or molecules). This is like low density.When the grade 4 and 5 students are all in the classroom there are 20 molecules in our classroom , which is higher density.
  •  Do you know what it would be called if the classroom was so full of molecules that we could not fit anymore molecules in? A) Solvent B) Saturated C) Substance
  •  The right answer is: B) Saturated
  •  Density is a physical property of a substance. A physical property is something about a substance that can be measured. The density of a substance is the same whether there is more of the substance or not.
  •  The opposite of physical property is chemical property. A chemical property of water is that it is NOT combustible.
  •  Watch this video on layering liquids http://www.youtube.com/watch?v=B3kodeQnQ vU
  • Video QuestionsAnswer the following questions:1. What is Density?2. The density of water is 1. Can you think of a liquid that would be less then the density of water?3. Salt water is more dense than pure water. Does this mean the salt water would sink or float?4. In the seven layer experiment, why did the different liquids not mix together?
