Cooling Curve Chart (Part 1)
• During exothermic reactions, heat is lost. Therefore, the phases go from gas to liquid to solid.
• The slanted lines show that:
1. The substance remains in the same
phase – solid, liquid, or gas.
a. Line AB: gas b. Line CD: liquid c. Line EF: solid
2. The temperature and kinetic energy are decreasing. The line is moving down in temperature.
