Document Summary
Temperature is a measure of the average speed of molecule movement in a substance. This movement is faster for higher temperatures and slower for lower temperatures. A measure of the movement of the molecules, Energy or the speed of movement of the molecules. Ex: air molecules are moving faster if the air is warm/hot. Ex: solid structure molecules vibrating faster = warm temperature. In a solid structure, the molecules are vibrating within the framework that they have. Eventually if you heat them enough, they will break free of those bonds and it combusts and starts to burn. Temperature of absolute zero: molecules are no longer moving or vibrating (minus 273 degrees) Different temperature scales were developed based the phases of water (celsius) and human comfort (fahrenheit). The fahrenheit scale was largely developed based on typical outdoor temperatures in england. Celsius (used in canada) was derived for scientific purposes. It is based on the boiling and freezing points of water.
