A Mollier chart if the thermodynamic properties is shown in which of the following diagrams?

• p-h diagram
• P-V diagram
• T-S diagram
• h-S diagram

The following are included in the first law of thermodynamics for closed system EXCEPT:

• internal energy
• heat transferred in and out of the system
• work done by or on the system
• kinetic energy

All processes below are irreversible except one. Which one?

• Inelastic deformation
• Heat conduction
• Elastic tension and release of steel bar
• Magnetization with hysteresis

The combination of conditions that best describes a thermodynamic process is given by which of the following? I. Has successive states through which the system passes II. When reversed leaves no change in the system III. When reversed leaves no change in the system or the surroundings IV. States are passes through so quickly that the surroundings do not

• I and IV
• I only
• I and II
• I and III

The sum of the energies of all the molecules in a system where energies appear in several complex forms in the:

• frictional energy
• potential energy
• kinetic energy
• internal energy

The Carnot refrigeration cycle includes all of the following process except:

• isentropic expansion
• isenthalpic expansion
• isothermal heating

• process irreversibility
• Reversible work

The following factors are necessary to define a thermodynamic cycle except:

• the means of doing work on the system
• high and low temperature reservoirs
• the working substance
• the time it takes to complete the cycle

All of the following terms included in the second law for open system except

• shaft work
• internal energy
• flow work
• average work

The following terms are included in the first law of thermodynamics for open systems except

• magnetic system
• work done by or in the system
• internal system
• heat transferred in and out of the system
