Answer 1

Answer:

UNDERSTANDS THE CONCEPT OF REVERSIBILITY                                        

Explanation:

Within thermodynamics, a reversal system refers to the process whose path can be restored to its old location by causing infinitesimal adjustments in any properties of the mechanism through its own surroundings. The mechanism is in thermal equilibrium because of its environment during the whole reversible cycle.

This makes no shift either in the process or the environment after being reversed. Since stopping the reversible cycle will take an endless amount of time, completely reversible systems are unlikely. Thus, from the above we can conclude that Eric's actions are demonstrating that he understands the concept of reversibility.
