Show answer & explanation
Correct answer: C — Intensive
Density is defined as mass per unit volume. Since it is independent of the amount of substance, it is an intensive property.
Q2. Consider a sample of pure water at equilibrium. Which of the following properties is an intensive property?
Show answer & explanation
Correct answer: C — Density of the water
Intensive properties are independent of the size or amount of the substance. Density is an intrinsic property of water and does not change regardless of how much water is measured. Mass, volume, and total heat content are extensive properties.
Q3. Which pair represents a set of extensive properties?
Show answer & explanation
Correct answer: A — Mass and Volume
Mass and Volume are extensive because they depend directly on the size of the system. Temperature, Pressure, and Density are intensive.
Q4. The density of a substance is an example of which type of property?
Show answer & explanation
Correct answer: D — Intensive property
Density is defined as mass per unit volume (mass/volume). Since it is independent of the amount of substance, it is an intensive property.
Q5. Which of the following physical quantities is an extensive property?
Show answer & explanation
Correct answer: D — Temperature
Extensive properties depend on the amount of matter. Temperature, pressure, and density are intensive properties. Mass and volume are extensive properties.
Q6. If the total volume of a system is doubled, what happens to its volume?
Show answer & explanation
Correct answer: A — It doubles
Volume is an extensive property. If the size of the system increases (doubled), its volume also doubles.
Q7. Which of the following statements correctly describes the difference between extensive and intensive properties?
Show answer & explanation
Correct answer: A — Extensive properties depend on the amount of substance, whereas intensive properties do not.
Extensive properties depend on the amount of substance, whereas intensive properties do not. This is the fundamental difference.
Q8. Which of the following properties of a system is considered extensive?
Show answer & explanation
Correct answer: A — Total volume
Extensive properties depend on the size or amount of the system. Total volume is extensive, while temperature and pressure are intensive.
Q9. Which of the following properties is considered intensive?
Show answer & explanation
Correct answer: D — Temperature
Intensive properties are those that do not depend on the amount of matter. Temperature is the standard example of an intensive property, while mass, volume, and total energy are extensive.
Q10. If a property does not depend on the size or extent of the system, it is classified as:
Show answer & explanation
Correct answer: A — Intensive
Properties that are independent of the size or extent of the system are called intensive properties.
Q11. Which of the following represents an extensive property of a thermodynamic system?
Show answer & explanation
Correct answer: B — Internal Energy
Extensive properties are those that depend on the size or extent of the system (e.g., mass, volume, total energy). Internal energy is an extensive property.
Q12. Which of the following quantities is an extensive property?
Show answer & explanation
Correct answer: A — Volume
Volume depends on the amount of matter present, making it an extensive property. Temperature, pressure, and specific heat capacity are intensive properties.
Q13. If the temperature of a gas changes, which property remains the same for that gas?
Show answer & explanation
Correct answer: D — Mass
Temperature is an intensive property. While the internal energy of a system changes based on its process, the temperature itself is an intrinsic property of the state of the system, remaining the same if the process is isothermal.
