  1. What is a pure substance?
    A pure substance is a kind of matter that cannot be separated into other kinds of matter by any physical or chemical process.
  2. What is a Homogeneous mixture
    any combination of substances that has uniform composition and properties
  3. What is a Heterogeneous mixture
    any combination of substances that does not have uniform composition and properties

    OR

    a mixture of physically distinct substances with different properties
  4. What is a Solution
    a gas, liquid, or solid that have other substances mixed together
  5. What is a Mechanical mixture
    A heterogeneous mixture of particles or masses distinguishable as such under the microscope or separable by filtration
  6. What is Suspension
    a system consisting of small particles kept dispersed by agitation (mechanical suspension) or by the molecular motion in the surrounding medium (colloidal suspension).
  7. What is a Colloid
    a substance made up of a system of particles with linear dimensions
  8. What is a Element
    one of a class of substances that cannot be separated into simpler substances by chemical means. See also chart under periodic table
  9. What is a Compound
    composed of two or more parts, elements, or ingredients
  10. What is Chromatography
    the separation of mixtures into their constituents by preferential adsorption by a solid, as a column of silica (column chromatography) or a strip of filter paper (paper chromatography) or by a gel
  11. What is a phase
    A par tof a Mechanical mixture
  12. What is Pascals law
    Pascal's law or the Principle of transmission of fluid-pressure states that "pressure exerted anywhere in a confined fluid is transmitted equally in all directions throughout the fluid
  13. What is Viscosity
    The amout of risistance it take for a object (Lets say a marble to fall to the bottom) The longer it takes for the marble to fall to the bottom, (Lets say to fall to the bottom of maple syrup) the longer it takes the more viscoity.
