Matter <ul><li>Definition: anything with the characteristics of mass and volume </li></ul>A human is considered matter because they take up space (volume) and they have mass.
Not Matter <ul><li>Definition: something that is unrelated to matter, and it itself is not categorized as matter </li></ul>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
Pure Substance <ul><li>Definition: matter that has only one type of particle </li></ul>Sugar is an example of a pure substance, as it has only one type of particle. * Pure substances are composed of elements and compounds
Element <ul><li>Definition: a pure substance that has only one kind of particle, substance cannot be any simpler </li></ul>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.
Compounds <ul><li>Definition: a pure substance that has two or more elements that makes up one type of particle </li></ul>Salt is a combination of the elements sodium and chloride, which makes it composed of two different elements which equal one type of particle
Mixtures <ul><li>Definition: any substance that has two or more pure substances </li></ul>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.
Heterogeneous Mixtures <ul><li>Definition: a type of mixture in which its components can be easily seen </li></ul>Soda is a type of heterogeneous mixture because the carbon dioxide is visible seperated from the liquid itself.
Homogenous Mixtures <ul><li>Definition: a type of mixture in which its components are well blended that it seems as one to the human eye </li></ul>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.
Mass <ul><li>Definition: the measure of the number of matter contained in an object, unlike weight </li></ul>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
Volume <ul><li>Definition: the amount of space an object takes up </li></ul>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.
Density <ul><li>Definition: mass per unit volume of a substance ( ex: its ability to float) </li></ul>A person swimming is an example of density as a person needs enough oxygen in their body to become less denser (lighter) than water
Viscosity <ul><li>Definition: the property of a fluid that goes against the force in which causes the fluid to flow </li></ul>Face powder is composed with miniscule types of fluid which depends on viscosity to be applied properly onto the face
State <ul><li>Definition: the states in which matter can be found, solid, liquid and gas </li></ul>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
Conductivity <ul><li>Definition: ability of a material to conduct heat or electricity </li></ul>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
Physical Changes <ul><li>Definition: the changing of the form or state of a substance but not the substance itself </li></ul>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
Chemical Changes <ul><li>Definition: a chemical reaction happening within a substance which changes it into a new substance with different properties </li></ul>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.
