Temperature: a measure of the _______________________ of individual molecules in matter. The point at which atomic and molecular motion in matter complete stops is _______________. As we shall see, its value differs in the three different temperature-measuring scales. Heat: a form of __________ that flows from one system or object to another because the two are at different temperatures There are three temperature scales: 1. Used in US: 2. Divided into 100 degrees using the decimal system (most countries use this): 3. Starts at absolute zero, so readings are proportional to the actual kinetic energy in a material: The temperature scales have three key measurement points: 1. 2. 3. 1.Melting point of ice: Fahrenheit (know for test): Celsius: (know for test): Kelvin: (do not need to know for test): 273 2.Boiling point of water: Fahrenheit (know for test): Celsius (know for test): Kelvin (do not need to know for test): 373 3.Point at which atomic motion stops: Fahrenheit (do not need to know for test): -459.4 Celsius (do not need to know for test): -273 Kelvin (know for test): The freezing point for water is not included as a key measurement point because it varies between _______________, depending upon its purity, volume, and conditions in the atmosphere. Which is FALSE? a) Temperature is a measure of the average amount of motion of individual molecules in matter b) Heat is a form of energy that flows from one system or object to another because the two are at different temperatures c) The freezing point for water varies is always 32 F. d)
