Solution
The correct options are
B Adiabatic
D Free expansion
Isothermal process :- Temperature remains constant (i.e.ΔT=0)Adiabatic process :- It is the process in which heat is not exchanged by system with the surroundings (i.e. Q=0)Free expansion :- In free expansion, the gas expands freely. Which means that the volume change is zero. So work done is zero. Also the heat transferred is zero, as the both chambers are insulated (i.e. Q=0)Cyclic :- It is a process in which the initial & final states of the system are the same.
