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

Hint: A system is that part in a universe that is selected for the purpose of experimental investigations. While that part of the universe other than the system is called the surrounding. Boundaries are present between the system and the surroundings.

Complete answer:
In thermodynamic study of chemistry, a part where all the reactions occur is the system and the part near the system is its surrounding. There are various types of systems in thermodynamics, like, open system, closed system, isolated system.
A closed system comprises an atmosphere where there can be no change of matter in between the system and the surroundings, but energy change can happen.
An open system is that system that is capable to exchange both energy and matter to the surroundings from the system.
An isolated system is that kind of system which can neither exchange matter nor any sort of energy from the system to the surroundings.
While, an isothermal process is that where the temperature change remains constant, that is $\Delta T=0$.
Another term adiabatic is used for the process which cannot exchange heat or energy with the surrounding. This is an example of a closed system.
Hence, an isolated system has no exchange of matter, work or energy.

So option C is correct.

Note:
Various thermodynamic processes occur when there is change in system from one state to another. These processes are isothermal process, adiabatic process, isochoric process, isobaric process. An open system has diathermic walls while a closed system has adiabatic walls.
