DESCRIPTION
3.3 Phase Changes Characteristics of Phase Changes A. One way to recognize a phase change is by measuring the temperature of the substance. B. Temperature DOES NOT change during a phase change. http://www.splung.com/heat/images/latentheat/phasechange.pngTRANSCRIPT
3.3 Phase Changes1. What are six common phase changes?2. What happens to a substance’s
temperature and a system’s energy during a phase change?
3. How does the arrangement of water molecules change during melting and freezing?
4. How are evaporation and boiling different?

3.3 Phase ChangesC. Energy is either absorbed or released during a phase change.1. Endothermic change-
energy is absorbedfrom its
surroundings.2. Exothermic change-
energy is released to
the surroundings.
