Question

System in which there is no exchange of matter, work or energy from surroundings is:

• A. closed
• B. adiabatic
• C. isolated
• D. isothermal

Answer 1

Answer: (C)

isolated

Closed System - The system in which only energy can be exchanged with the surrounding.

Adiabatic - The process in which heat is not exchanged by the system with the surroundings, i.e., $Q=0$.

Isolated - The system in which neither energy nor matter can be exchanged with the surroundings.

Isothermal - The temperature remains constant, i.e., $\Delta T=0$.

Hence, the correct answer is option $\text{C}$.
