Unformatted text preview: matter exist simultaneously. Generally occurs at low temperatures and pressures. Heating/Cooling Curves: illustrate how changing the temperature can alter the phase of matter. When a substance is in a phase, adding energy increases the temperature. When a phase change occurs, energy is added, but the temperature remains constantwhy? The additional energy is used to break the intermolecular forces between molecules. Conclusions: T and P can be used to manipulate phase Different phases can be reached at a variety of temperature and pressure conditions At the triple point, all three phases of matter exist simultaneously Heating and cooling curves show the impact of temperature only on a substance At phase changes, temperature remains constant...
