Overview
Phase diagrams are essential tools in chemistry and material science, providing insights into how substances behave under varying conditions of temperature and pressure. They illustrate the relationships between different phases, such as solid, liquid, and gas, and highlight critical points like the...
Key Terms
Example: Water exists as solid ice, liquid water, and gas steam.
Example: The triple point of water occurs at 0.01°C and 611.657 pascals.
Example: Above the critical point, water cannot exist as a liquid.
Example: Melting is a phase transition from solid to liquid.
Example: F = C - P + 2, where F is degrees of freedom, C is components, and P is phases.
Example: At equilibrium, the rate of evaporation equals the rate of condensation.
