Question:
Identify the correct statements:
I. Energy of an isolated system is constant
II. In a closed system, exchange of both energy and matter is possible
III. Enthalpy is extensive
Identify the correct statements:
I. Energy of an isolated system is constant
II. In a closed system, exchange of both energy and matter is possible
III. Enthalpy is extensive
I. Energy of an isolated system is constant
II. In a closed system, exchange of both energy and matter is possible
III. Enthalpy is extensive
Show Hint
Isolated: no energy/matter transfer.
Closed: energy only.
Open: energy and matter.
Check definitions carefully.

- II, III only
- I, II only
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
• Isolated system: no exchange of energy/matter → energy constant.
• Closed system: only energy exchange, matter cannot cross boundary → statement II false.
• Enthalpy depends on system size → extensive.
• Closed system: only energy exchange, matter cannot cross boundary → statement II false.
• Enthalpy depends on system size → extensive.

- Three moles of an ideal gas undergoes a cyclic process ABCA as shown in the figure. The pressure, volume and absolute temperature at points A, B and C are respectively \((P_1, V_1, T_1)\), \((P_2, 3V_1, T_1)\) and \((P_2, V_1, T_2)\). Then the total work done in the cycle ABCA is (R- Universal gas constant).
