Document Summary
Adiabatic process: heat is not transferred into or out of system. Boiling point: temperature at which liquid under fixed pressure converts to vapor. Carnot cycle: system undergoing cyclical process with 4 reversible changes. Carnot engine: most efficient heat engine which carries out the. Critical point: temperature and pressure at which liquid and vapor become identical. Cyclical process: repeats sequence of changes in system. Enthalpy (h): quantity of heat in substance/unit mass under constant pressure. Entropy (s): thermodynamic property related to degree of disorder in a system. Heat (q or q): form of energy transfer resulting from temperature difference. Heat capacity (c): total amount of heat to produce a 1 degree rise in temperature of a given substance. Internal energy: total kinetic and potential energy at the molecular level. Isobaric process: process involving constant pressure in the system. Latent heat of fusion (lf): amount of heat needed to convert unit mass of solid to liquid at same temperature.
