Question

Adiabatic Process is that in which no transfer of __________ occurs?
(A) Energy
(B) Mass
(C) Both A and B
(D) none

Answer 1

As we know that the system must be perfectly insulated from the surroundings, only during adiabatic process, where the system neither receives nor gives heat to its surroundings. No process can be made truly adiabatic. There will always be some small amount of heat transfer regardless of how perfect you make the apparatus.

Complete step by step answer:
Adiabatic Process is one in which there is no transfer of heat energy occurs, that is represented numerically as:
$Q = 0$
where, $Q$ is the heat energy of the thermodynamics system.
And, also in adiabatic processes, mass does not factor in or the occurrence during this process.
An adiabatic process is a sort of thermodynamic process that happens without the passage of heat or mass between the thermodynamic system and its environment in thermodynamics. An adiabatic process, unlike an isothermal process, only sends energy to the environment as work.
There are the ways or the condition, in which adiabatic process can occur are as follows:-
(i) First, a gas cylinder can be totally encased in thermal insulation (such as thick pieces of Styrofoam), allowing the environment to interact mechanically with the gas by pushing or pulling on the insulated piston, but there is no thermal interaction.
(ii) Second, the gas can be rapidly expanded or compressed, a process known as adiabatic expansion or compression. There is virtually no time for heat to be transmitted between the gas and the environment in a fast operation.
Hence, the correct option is (A) Energy.

Note: We will also discuss the effect of the fastness or quickness of the Adiabatic process. Therefore, adiabatic processes are so quick that there is no heat transmission between the environment and the system. At constant pressure, the specific heat is greater than the specific heat at constant volume.
