The sequence of processes that eventually returns the working substance to its original state is known as
Thermodynamic cycle can be defined as a series of state changes such that the final and initial state is identical.
A system and its environment put together form universe called as
An isolated system is one in which there is no interaction of system with the surrounding, for isolated system
δQ = 0
δW= 0
The first law gives
δQ = dU + δW
dU = 0
U = constant
The energy of isolated system is constant.
Which one ofthe following is extensive property of a thermodynamics system
The properties which are mass independent are intensive properties and those which are mass dependent are extensive properties.
Volume depends upon the amount of matter present in the system. Hence, it is an extensive property.
Which of the following quantities is not the property of the system
Since heat transfer is the path function hence it is not the property of the system.
Open system: Both mass and energy transfer takes place
Closed system: No mass transfer, energy transfer may takes place
Isolated system: Neither energy nor mass transfer takes place.
The value of an extensive property is extensively dependent on
Which of the following are intensive properties
1. Kinetic energy
2. Specific enthalpy
3. Pressure
4. Entropy
Codes:
For a system to be in thermodynamic equilibrium the system and its surroundings are to be in
A system said to be in thermodynamic equilibrium with surrounding if:
It is in thermal, chemical as well as mechanical equilibrium with the surrounding.
And when system is in thermodynamic equilibrium there won't be any spontaneous change.
