Question

System where there is no exchange of work, matter, energy from the surrounding is known as?
(A) Closed
(B) Adiabatic
(C) Isolated
(D) Isothermal

Answer 1

There are few systems that operate in our environment through which several reactions take place and the major chemical processes are happening around us with the help of these systems only. The type of system chosen for a particular reaction to take place depends on the requirements of that process.

Complete answer:
To answer this question, we need to understand these systems in brief and their criterias.
So, let’s start, a closed system is the system, in which there is no transfer of matter from the system with the surrounding. The system is separated from the surrounding with the physical walls.
According to different concepts of physics, chemistry or engineering, the transfer of energy may or may not be allowed.
Now, coming to our next system i.e. Adiabatic.
Adiabatic process can be defined as the system in which there is no transfer of heat with the surrounding. Though the temperature of the adiabatic system does not remain constant, there is no heat transfer from the surroundings.
Coming to the next system i.e. Isolated system.
In the isolated system, there is no exchange of heat, matter or energy from the surrounding matter.
Therefore, based upon the above discussion, the correct answer is option C i.e. isolated system. Therefore, System where there is no exchange of work, matter, energy from the surrounding is known as an isolated system.

Note:
Whereas, in the isothermal process, it can be defined as a thermodynamic process in which the temperature of the system remains constant, however the transfer of heat with the surrounding atmosphere takes place but very slowly and steadily.
