Study Notes
Phase Diagrams
- A P-T diagram represents the relationship between pressure and temperature in a unary system, which is a system consisting of a single pure substance.
Solubility Limit
- The solubility limit in a sugar-water solution refers to the maximum amount of sugar that can dissolve in water at a given temperature.
Phase Diagram Components
- Components in phase diagrams refer to the minimum number of independent species required to describe the composition of all the phases present in a system.
Heterogeneous Systems
- A heterogeneous system in the context of phase diagrams is a system that consists of two or more phases, such as a mixture of solid and liquid.
Temperature Effect on Phases
- Altering temperature can affect the number of phases in a system, as different phases may become stable or unstable at different temperatures, leading to a change in the number of phases present.
