  • 1. Real Life Chemistry
    • By: Jasmine Xie
  • 2. Table of Contents
    • Definitions of:
    • Matter
    • Not Matter
    • Pure Substance
    • Element
    • Compounds
    • Mixtures
    • Heterogeneous Mixtures
    • Homogeneous Mixtures
    • Mass
    • Volume
    • Density
    • Viscosity
    • State
    • Conductivity
    • Physical Changes
    • Chemical Changes
  • 3. Matter
    • Definition: anything with the characteristics of mass and volume
    A human is considered matter because they take up space (volume) and they have mass.
  • 4. Not Matter
    • Definition: something that is unrelated to matter, and it itself is not categorized as matter
    Thoughts do not take up space (volume), as well it does not have mass, it is merely a concept that someone thinks up, meaning it is not of matter
  • 5. Pure Substance
    • Definition: matter that has only one type of particle
    Sugar is an example of a pure substance, as it has only one type of particle. * Pure substances are composed of elements and compounds
  • 6. Element
    • Definition: a pure substance that has only one kind of particle, substance cannot be any simpler
    Silver is a type of pure substance which is an element, there for it only has one kind of particle. Pure silver necklaces like these are a good example of an element.
  • 7. Compounds
    • Definition: a pure substance that has two or more elements that makes up one type of particle
    Salt is a combination of the elements sodium and chloride, which makes it composed of two different elements which equal one type of particle
  • 8. Mixtures
    • Definition: any substance that has two or more pure substances
    The substance that makes a T.V screen glow is made of a mixture of metal compounds to create the proper wavelength. One of the pure substances include Phosphors.
  • 9. Heterogeneous Mixtures
    • Definition: a type of mixture in which its components can be easily seen
    Soda is a type of heterogeneous mixture because the carbon dioxide is visible seperated from the liquid itself.
  • 10. Homogenous Mixtures
    • Definition: a type of mixture in which its components are well blended that it seems as one to the human eye
    Grape wine contains mixtures of alcohol, grape juice, sugar and many other components, but it is so well mixed that the components can be only seen as a red liquid.
  • 11. Mass
    • Definition: the measure of the number of matter contained in an object, unlike weight
    These two beakers are of the same shape and size, however they weigh differently, meaning even if two objects are similar, their mass may be different
  • 12. Volume
    • Definition: the amount of space an object takes up
    Without me or the clothes, the closet is an empty space, but once the clothes and I are placed within, we take up the once available space in the closet, meaning we have volume.
  • 13. Density
    • Definition: mass per unit volume of a substance ( ex: its ability to float)
    A person swimming is an example of density as a person needs enough oxygen in their body to become less denser (lighter) than water
  • 14. Viscosity
    • Definition: the property of a fluid that goes against the force in which causes the fluid to flow
    Face powder is composed with miniscule types of fluid which depends on viscosity to be applied properly onto the face
  • 15. State
    • Definition: the states in which matter can be found, solid, liquid and gas
    An ice cube is water in a solidi -fied state as it is fro-zen Water, is water in a liquid state as it flows easily Steam is a gaseous state of water as it is water vapor
  • 16. Conductivity
    • Definition: ability of a material to conduct heat or electricity
    A boiling pot can absorb heat and use it to cook, mean-ing it has conductivity A wire is used to transmit electricity, meaning it has conduc-tivity
  • 17. Physical Changes
    • Definition: the changing of the form or state of a substance but not the substance itself
    Crumpling and ripping the tin foil changes its form, but not itself as it is still tinfoil neverthe-less The part of the paper with absorbed water changes its form, as it is softer, however it is still paper
  • 18. Chemical Changes
    • Definition: a chemical reaction happening within a substance which changes it into a new substance with different properties
    Once the paper is burned, its properties or compo-nents are changed, making it a new substance called burnt paper. Once the egg is fried, it becomes cooked and no longer liquid, its components are changed during the frying, thus the name, fried eggs.
