Remember These in Thermodynamics

1. Thermodynamics is that branch of science which deals with energy transfer
2. A system may be closed, open or isolated system
3. A homogeneous system is one which consists of a single phase
4. A heterogeneous system is one which consists of two or more phases.
5. A property of a system is a characteristic of the system which depends upon its state, but not upon how the state is reached
6. Intensive properties do not depend on the mass of the system
7. Extensive properties depend on the mass of the system.
8. When a path is completely specified then the change of state is called a process.
9. A system is in thermodynamic equilibrium if there is no change in any thermodynamic properties of a system where it is isolated from its surroundings
10. A quasi static process can be viewed as a sufficiently slow process which allows the system to adjust itself internally so that properties in one part of the system do not change any faster than those at other parts. .
11. The energy which crosses the system boundaries is called transient energy
12. Temperature is an intensive property of a thermodynamic system. -
13. At absolute zero temperature the volume of a gas becomes zero
14. The absolute scale related to Celsius scale is known as Kelvin -scale.
