Also Assesses Not Applicable Multiple Choice Item Types Cognitive Moderate, High Complexity Type Benchmark The student will be able to describe the process of phase changes in Clarification matter in terms of particle motion, energy, and attraction of the particles in the sample of matter. The item should not involve plasma as a phase. Content Limits Stimulus Diagram, table, text Attributes Response None Specified Attributes Kinetic molecular theory, phase transition, molecules, matter, phase Content Focus change, solid, liquid, gas, motion, particles, melting, boiling, vapor, temperature, heat, energy, kinetic energy A sample of water is heated in a beaker until it begins to boil and turn to Sample Item steam. Which of the following best describes the transition of liquid water to steam? The particles gain so much energy, the attraction between them cannot hold them together and they leave the surface of the liquid to travel into the air. The particles gain so little energy, the attraction between them cannot hold them together and they leave the surface of the liquid to travel into the air. The particles in the water gain energy to begin to move in a more organized way, causing them to leave the surface of the water and travel into the atmosphere. The motion becomes so random and chaotic there is not particles’ more room for them to vibrate and they are flung into the air
