Number Relate temperature to the average molecular kinetic energy. Benchmark Also Assesses None Specified Item Types Multiple Choice Moderate Cognitive Complexity Type Benchmark The student will identify that temperature is a measure of the average kinetic energy of the particles. Clarification The student will identify that the temperature of a substance increases or decreases with an increase or decrease in the average kinetic energy of the particles of the substance. The student will recognize that the internal energy of an object includes the energy of random motion of the and molecules, often object’s atoms referred to as thermal energy. Content Limits The student should not compare and contrast states of matter and the motion of their particles. The student should not address differences in the Kelvin, Celsius, and Fahrenheit scales. Stimulus Illustrations, descriptions. Attributes Response None Specified Attributes Temperature, heat, matter, atoms, molecules, energy, Fahrenheit, Celsius, Content Focus Kelvin, particles, kinetic energy, thermal energy. Sample Item The temperatures of two identical liquids are taken. Liquid A has a temperature of 25.5 degrees C and Liquid B has a temperature of 45.1 degrees C. What best describes the difference between the two liquids?
