4. System,Boundary, Surroundings System -A thermodynamics system is defined a definite space or area on which the study of Energy Transfer and Energy conversions is made Boundary –The system and surrounding are separated by boundary. It may be fixed or movable or imaginary.It will not occupy any volume or mass in space

5. Surroundings - Anything outside the system which affects the behaviour of the system is known as surroundings Control volume – A specified large number thermal device has mass flow in and out of a system called as control volume Control surface – Both mass and Energy can cross the boundary of a control volume which is called control surface

6. Open,Closed,Isolated Systems

7. Classification of thermodynamics systems open, closed, Isolated systems Open system - One in which Both Energy and mass cross the boundaries of the system. Closed system - One in which mass does not cross boundaries of the system, though energy may do so. Isolated system - one in which neither mass nor energy crosses the boundaries of the system.
