Document Summary
Temperature: the measure of the movement of matter. Matter: has mass and occupies space living and non-living things. Energy: not matter, must be measured empirically, measure of what matter does. Matter is based on whether its shape and volume are definite or indefinite. Physical states of matter: solid: definite shape and volume, liquid: definite volume, indefinite shape, gas: indefinite volume, indefinite shape. Ice water gas water (constant chemical interactions) The current state of matter is dependant on: temperature: the higher the temperature, the faster the molecules move, surrounding pressure: the number of molecules crammed in one place, strength of the chemical bonds. There are two different characteristics of a substance: physical: observations made without changing the basic identity; a new chemical is not formed. The way a substance undergoes or resists change to form a new substance. Most often the result of a reaction with another substance. Changes to the chemical composition: methane reacts with oxygen to form.
