Matter & Properties of Matter

Matter anything that has mass and takes-up space the quantity of matter present mixtures and substances of the same kind of different kinds

Matter Matter- Mass- All matter can be divided into two categories: Homogeneous- Heterogeneous-

Mixtures definitions CAN be separated by physical means (heating, cooling, sorting, filtering) Homogeneous & Heterogeneous

Mixtures Mixture- 2 categories of mixtures:

More on Mixtures Homogeneous: Example: Heterogeneous: Examples:

Mixtures definitions is visibly the same throughout   Ex. salt water, Kool-Aid, milk is visibly different throughout; different samples may not be exactly alike ex. Salad dressing, chicken noodle soup

  Pure Substance-   Two Categories:   Element:   Example:   Compound:   Examples:

  CAN NOT be separated by physical means, ex: heating, cooling, sorting, filtering   Elements & Compounds   contains one kind of matter   Ex:hydrogen, oxygen, copper   a substance made of two or more elements that cannot be separated by physical means.   Ex: water, carbon dioxide, salt, and sugar

States of Matter What determines the state of the matter? Depends on the amount of energy of the particles Kinetic energy (E k ): energy of motion How fast are the particles moving? Depends on temperature

Four States of Matter Solid Liquid Gas Plasma

States of Matter Solid: Ek?Ek? molecular behavior? Liquid: E k ? molecules can slip out of their fixed position

States of Matter definite volume, definite shape LOW E k molecules vibrate in position definite volume, NO definite shape (can change shape easily) Moderate amount of E k molecules can slip out of their fixed position

States of Matter Gas: NO definite volume, NO definite shape HIGH E k molecules can move freely Plasma: Most common state of matter in the universe, it is rarely found on Earth VERY HIGH E k

States of Matter Gas: E k ? Molecule behavior? Plasma: Ek?Ek?
