Hati is the answer I hope this helps, be sure to answer correctly
The correct answer is can be reversed with no net change in either system or surroundings
Reversibility is a property that expresses the possibility of making the physical processes run in the opposite direction, infinitely varying the conditions that cause them.
The concept of reversibility has great importance in thermodynamics (in the foundation of its second principle), since it is the only type of processes that use the least amount of energy possible; thus, reversibly, the physical processes give their greatest performance.
In practice, it is not possible to obtain a completely reversible evolution of a process, because for this to happen, it should take place in an infinitesimal way, and, therefore, take an infinite time to complete. However, in order to obtain the highest possible efficiency, motors, machines, etc., are designed in such a way that the processes carried out on them are extremely similar to reversible processes.
The type of validity that she needs to show to demonstrate that her questionnaire assesses loneliness and not depression or even low self-esteem is that she should have a <span>Discriminant validity. A discriminant validity is the one responsible for testing measurements that are not related in some way in which this will differentiate loneliness and depression that would make her study to be more discernible.</span>
