CHMB20H3 Chapter Notes - Chapter 4: Chemical Potential, Viscosity, Molar Volume
Document Summary
Phase: form of matter that is uniform throughout in chemical composition and physical state. The thermodynamic analysis of phases is based on the fact that at equilibrium, the chemical potential of a substance is the same throughout the sample, regardless of how many phases are present: chemical potential (m. ): measure of the potential that a substance has for undergoing change in a system and is synonyms with molar gibbs energy (m. At normal boiling point, temperature where external pressure is. Freezing temperature: because a substance melts at exactly the same temperature as it freezes, melting temperature is the same as its freezing temperature. temperature. Normal freezing point (tf): freezing temperature when pressure is 1 atm. Standard freezing point (ts): freezing point when pressure is 1 bar: triple point: a point at which the three phase boundaries meet; it occurs at a single definite pressure and temperature characteristic of the substance.
