Question

It is given that a thermodynamic system changes from state A to state B and then back to state A. It is given that the process is reversible. Choose the correct statements.

• A. The states occurring between A to B are the same as states occurring between B to A.
• B. The states occurring between A to B may be different from the states occurring between B to A.
• C. The energy required for transition from state A to state B is same as the energy required for the transition from state B to state A.
• D. The states occurring between A to B cannot be measured.

Answer 1

The correct option is A The states occurring between A to B are the same as states occurring between B to A.

In thermodynamics, a reversible process is a process whose direction can be "reversed" by inducing infinitesimal changes to some property of the system via its surroundings, with no increase in entropy. Throughout the entire reversible process, the system is in thermodynamic equilibrium with its surroundings.a thermodynamic system changes from state A to state B and then back to state A. It is given that the process is reversible the states occurring between A to B are the same as states occurring between B to A
