Using the phase change graph above to answer the following questions below. For each the segments below answer the assigned questions. Questions will center around change in temperature, kinetic energy, particle speed, bonds breaking or forming. Also, make use of the following vocabulary words as they apply for each of the segments below GAS, SOLID, LIQUID, MELTING, VAPORIZATION, FREEZING, CONDENSATION. 1. Is this change an endothermic or exothermic process? 2. Describe the partide speed during this segment. B-C 3. What process is taking place during this segment? 4. Is thermal energy being added or removed during this se gment? 5. Explain why the temperature is not changing during this segment. 6. Is the process during this segment endothermic or exothermic?
