β Basic Terminology:
βSystem- Part of the universe under investigation.
βOpen System- A system which can exchange both energy and matter with its surroundings.
βClosed System- A system which permits passage of energy but not mass, across its boundary.
βIsolated system- A system which can neither exchange energy nor matter with its surrounding.
βSurroundings- Part of the universe other than system, which can interact with it.
βBoundary- Anything which separates system from surrounding.
βState variables- The variables which are required to be defined in order to define state of any system i.e. pressure, volume, mass, temperature, surface area, etc.
βState Functions- Property of system which depend only on the state of the system and not on the path. Example: Pressure, volume, temperature, internal energy, enthalpy, entropy etc.
βIntensive properties- Properties of a system which do not depend on mass of the system i.e. temperature, pressure, density, concentration,
βExtensive properties- Properties of a system which depend on mass of the system i.e. volume, energy, enthalpy, entropy etc.
βProcess- Path along which state of a system changes.
βIsothermal process- Process which takes place at constant temperature
βIsobaric process- Process which takes place at constant pressure
βIsochoric process- Process which takes place at constant volume.
βAdiabatic process- Process during which transfer of heat cannot take place between system and surrounding.
βCyclic process- Process in which system comes back to its initial state after undergoing series of changes.
βReversible process- Process during which the system always departs infinitesimally from the state of equilibrium i.e. its direction can be reversed at any moment.
βIrriversible Process- This type of process is fast and gets completed in a single step. This process cannot be reversed. All the natural processes are of this type
