Unformatted text preview: Chapter Five: Global Temperatures Temperature Concepts and Measurements o Heat a form of energy that flows from one system or object to another because the two are at different temperatures. o Temperature measure of the average kinetic energy of individual molecules in matter. Feel the effects as sensible heat transfer from warmer objects to cooler objects. o Temperature and heat are related because changes in temperature are caused by the absorption or emission of heat energy. o Heat Energy frequently used to describe energy that is added to or removed from a system or substance. Temperature Scales o Absolute Zero temperature at which all atomic and molecular motion in matter completely stops. -273C -459.4F 0 Kelvin o Fahrenheit Melting Point - 32F Boiling Point - 212F o Celsius Melting Point 0C Boiling Point - 100C o Kelvin Melting Point 273 K Boiling Point 373 K Measuring Temperature o Mercury Thermometer/Alcohol Thermometer sealed glass type that measures outdoor temperatures. When fluids are heated, they expand, upon cooling, they contract. o Mercury Minimum/Maximum Thermometer Stores readings of the days highest and lowest temperatures until reset....
