| A | B |
|---|
| substance | single kind of matter with a specific set of properties, pure, can be chemically combined |
| oxygen, Nickel, water | examples of substances |
| mixture | two or more substances mixed together but keeping their own properties and are not chemically combined |
| heterogeneous | mixture that does not appear the same throughout |
| suspension | type of heterogeneous mixture where small particles are present in liquid or gas and will settle out after enough time |
| sand/water, salad dressing; oil/vinegar | examples of suspension |
| heterogeneous | least mixed mixture |
| homogeneous | type of mixture that appears the same throughout |
| salad, tacos, soil, chex mix, granite | examples of a heterogenous mixture |
| colloid | type of homogeneous mixture in which the particles are mixed but not dissolved |
| solution | best mixed mixture |
| milk, fog, smoke, glue | examples of colloids |
| solution | type of homogeneous mixture when one substance dissolves in another |
| element | pure substance that cannot be broken down into any other substances by chemical or physical means |
| atom | basic particle from which all elements are made |
| salt water, iced tea, air, brass, soda | examples of solutions |
| element | simplest substance |
| crystalline solid | a solid that is made up of crystals in which particles are arranged in a regular, repeating pattern |
| amorphous solid | solid made up of partices that are not arranged in a regular pattern; plastics, rubber and glass are examples of these |
| atoms | elements are different because their ______ are different |
| molecules | groups of two or more atoms held together by chemical bonds |
| compounds | pure substance made of two or more elements chemically combined in a set ratio. |
| plasma | gas-like state of matter consisting of a mixture of free electrons and atoms that are stripped of their electrons |
| atom | smallest part of an element that has the properties of that element |
| colloid | type of mixture that has suspended particles and scatters light |
| solutions | mixture in which particles are too small to scatter light |
| liquid boils, evaporates, condenses and collects in a cooling tube | 4 steps of distillation |
| mass | how much matter an object contians |
| stars, comet's tail, fluorescent light when it is turned on, sun | where plasma can be found |
| sublimation | state change directly from a solid to a gas; dry ice and snow can change directly from a solid to a gas |
| surface tension | result of an inward pull amorng the molecules of a liquid that brings the molecules on the surface closer together; causes the surfact to act as if it has a thin skin |
| gas | state of matter that has neither a definite shape or volume |
| nickel, iron, cobalt | 3 elements that are most magnetic |
| solid | state of matter with a definite shape and volume; particles vibrate in place |
| liquid | state of matter in which particles are free to move and does not have a definite shape but has a devinite volume |
| chemical property | describes a substance's ability to change into a different substance |
| Physical property | characteristics of a substance that can be observed without changing the identify of the substance |
| crystal | snowflakes and table salt are examples of this |
