Matter+Project

Matter is classified as anything with mass and volume. It can have a constant composition (Substance), or a varying composition (Mixture). The smallest thing classified as matter us ab atom, which is the smallest part of an element. Elements can be combined to form compounds There are also Heterogeneous Mixture s such as sand. Heterogeneous Mixtures are made up of more than one phase. Then there are Homogeneous Mixtures that are also called solutions. Solutions are made up of only one phase. An example would be salt water.

A phase is any region of a material that has its own set of properties. In a chocolate chip cookie the dough and the chips have different properties. Therefore they represent separate phases. Pure gold, which is an element, would only contain one phase. Italian dressing would clearly represent several phases, while a solution of salt water may only contain one phase.

All matter has physical properties. The physical properties of matter include: appearance, texture, color, odor, melting point, boiling point, density, solubility, polarity, and many others. An example would be the boiling point of water which is 212 degrees Fahrenheit (100 degrees Celsius), or that rocks are hard. The physical properties of matter changes throughout its phases, such as ice has a different texture and density than normal water. However, they also have properties in common with each other, such as colour, odor, boiling point. All matter as at least one physical property shared with another piece of matter
