An isolated thermodynamic system executes a process. Choose the correct statement(s) from following A. No heat is transferredB. No work is doneC. No mass flows across the boundary of the systemD. No chemical reaction takes place within the system
For an isolated system, there is no flow of mass as well as energy across the system boundary hence options A, B, and C are correct.
Example of an isolated systems is perfectly insulated thermos flask.
