What is Process?
A description in the manner in which a change in state
occurs.
What is Isobaric
process?
Any process in which the pressure of a gas remains constant
What is Isochoric
process?
Any process in which the volume of a gas remains constant
What is Isothermal
process?
Any process in which the temperature of a gas remains
constant
What is Adiabatic?
The expansion or compression of a gas without a gain or loss
of heat.
What is a steady flow
process?
Steady flow means that the rates of flow of mass and energy
across the control surface are constant.
Source is a thermal reservoir, which supplies heat to the
system and sink is a thermal reservoir, which takes the heat from the system.
What is homogeneous
and heterogeneous system?
The system consist of single phase is called homogeneous
system and the system consist of more than one phase is called heterogeneous
system.
What is reversible
process in thermodynamics?
A process which is
carried out infinitesimally slowly so that changes occurring in the direct
process can be exactly reversed without disturbing the equilibrium.
A process in which
both the system and its environment can be returned to exactly the states they
were in before the process occurred.
A reversible process is one, which is performed in such a
way that at the conclusion of process, both system and surroundings may be
restored to their initial state, without producing any changes in rest of the
universe.
What is Pressure-volume
(PV) diagram?
A graph of pressure vs. volume which gives an indication of
the work done by or on a system, and the energy transferred during a process
What is the irreversible
process?
The mixing of two substances and combustion also leads to
irreversibility. All spontaneous process is irreversible.
