What determines whether a physical property is classified as intensive or extensive?
The dependency of the property on the system size or extent
What is a quasi-equilibrium process?
A process where the intermediate steps are all close to equilibrium

Mass
What is a characteristic of a quasi-equilibrium process?
The intermediate states of the process can be characterized using state variables

A series of states through which a system passes during a process
What happens to the hardness of a diamond when it is cut into smaller pieces?
It remains the same
Which of the following is an example of a state variable?

One depends on the system size, while the other does not
What is the term for the concept that smaller, non-interacting identical subdivisions of the system may be identified?
Thermodynamic concept
What is a characteristic of state variables?
They are path-independent
Which of the following is NOT a state variable?

What is a common use of PV diagrams in thermodynamics?
To estimate the net work performed by a thermodynamic cycle
What is a characteristic of a state variable?
It returns to its original value after a cycle
What is the purpose of an indicator diagram in a steam engine?
To estimate the performance of the engine
What is required for a process to be considered reversible?
The system must be in thermodynamic equilibrium throughout
What is the relationship between the area enclosed by the PV curve and the work done by the system?
The area is equal to the work done
What is plotted on the x-axis in some cases instead of volume in a PV diagram?
Specific volume
What happens to the system and its surroundings after a reversible cycle?
The system and its surroundings are exactly the same
Why is it necessary to calculate the integral of the pressure with respect to volume?
To exactly calculate the work done by the system
Why are perfectly reversible processes impossible?
Because they require an infinite amount of time
What is an alternative definition of a reversible process?
A process that can be reversed and causes no change in either the system or its surroundings

What does it mean for a process to 'take place' in thermodynamic terms?
For the system to undergo a change in state
An isobaric process is a thermodynamic process in which the volume remains constant.
False
Isochoric process is exemplified by the heating or the cooling of the contents of a sealed, elastic container.
False
An adiabatic process is a process that allows the transfer of heat or matter between a system and its surroundings.
False
In an isobaric process, the volume is allowed to expand or contract to neutralize any pressure changes.
True
An isochoric process is a thermodynamic process during which the pressure of the closed system remains constant.
False
Adiabatic transfer provides a rigorous conceptual basis for the theory used to expound the second law of thermodynamics.
False
In an isochoric process, the volume of the closed system can expand or contract freely.
False
An isobaric process is a thermodynamic process in which the temperature remains constant.
False
