  • 1. Real Life Chemistry By: Jasmine Xie
  • 2. Table of Contents Definitions of: • Density • Matter • • Viscosity State • Not Matter • Conductivity • Pure Substance • Physical Changes • Element • Chemical Changes • Compounds • Mixtures • Heterogeneous Mixtures • Homogeneous Mixtures • Mass
  • 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 Water, cube is is water water in a in a liquid solidi- state fied as it Steam is a gaseous state flows state of water as it as it easily is water vapor is fro- zen
  • 16. Conductivity Definition: ability of a material to conduct heat or electricity A boiling A wire is pot can used to absorb transmit heat electricity, and meaning it use it has to conduc- cook, tivity mean- ing it has conduc tivity
  • 17. Physical Changes Definition: the changing of the form or state of a substance but not the substance itself The part of the paper Crumpling with and ripping absorbed the tin foil water changes its changes form, but its form, not itself as as it is it is still softer, tinfoil however neverthe- it is still less paper
  • 18. Chemical Changes Definition: a chemical reaction happening within a substance which changes it into a new substance with different properties Once the Once the paper is egg is fried, burned, its it becomes properties cooked and or compo- no longer nents are liquid, its changed, making it components a new are changed substance during the called frying, thus burnt the name, paper. fried eggs.
