1. Which quantity is an intensive property?
,A. Mass
B. Volume
C. Number of moles
D. Temperature
Answer: D. Temperature
Temperature does not depend on the amount of material present,
making it an intensive property.
2. Which quantity is an extensive property?
A. Pressure
B. Density
C. Volume
D. Temperature
Answer: C. Volume
Volume depends on the quantity of material in the system and is
therefore extensive.
3. A closed system is one in which:
A. Neither mass nor energy crosses the boundary
B. Mass cannot cross the boundary, but energy may cross
C. Mass crosses freely but energy cannot cross
D. Both mass and energy must cross
Answer: B. Mass cannot cross the boundary, but energy may cross
A closed system contains a fixed amount of matter but can exchange
heat and work with its surroundings.
4. An isolated system permits:
,A. Mass transfer only
B. Heat transfer only
C. Work transfer only
D. Neither mass nor energy transfer
Answer: D. Neither mass nor energy transfer
An isolated system exchanges neither matter nor energy with its
surroundings.
5. The SI unit of pressure is:
A. atm
B. bar
C. Pa
D. psi
Answer: C. Pa
The pascal (Pa), equivalent to N/m², is the SI unit of pressure.
6. One mole of an ideal gas obeys which equation?
A. (PV=RT)
B. (PV=ZRT) only
C. (PV=RT^2)
D. (P=VRT)
Answer: A. (PV=RT)
For one mole of an ideal gas, the ideal-gas equation is (PV=RT).
7. For an ideal gas, the compressibility factor (Z) is:
A. 0
B. 0.5
, C. 1
D. Dependent only on temperature
Answer: C. 1
By definition, an ideal gas has (Z=PV/RT=1).
8. The compressibility factor is defined as:
A. (Z=RT/PV)
B. (Z=PV/RT)
C. (Z=PV/R)
D. (Z=PT/RV)
Answer: B. (Z=PV/RT)
The compressibility factor compares real-gas behavior with ideal-gas
behavior.
9. A process occurring at constant temperature is called:
A. Isobaric
B. Isochoric
C. Isothermal
D. Adiabatic
Answer: C. Isothermal
An isothermal process has constant temperature.
10. A process occurring at constant pressure is:
A. Isobaric
B. Isothermal
C. Isochoric
D. Isentropic
