Which of the following statements about entropy is true? a. entropy increases going from one trophic level to another. b. increases in entropy lead to reversible processes. c. a system’s work output is limited when changes in entropy do not occur. d. all of the above

A system’s work output is limited when changes in entropy do not occur.

Explanation:

The randomness in a system is called the entropy of the system. It is denoted by symbol S. Mathematically, it can be written as :

Where

is the thermal energy

T is the temperature of the system

According to second law of thermodynamics the entropy of any system never decreases. It always increases or remains the same. It also depends directly on the amount of heat.

So, the correct option is (c) " A system’s work output is limited when changes in entropy do not occur ".      

your answer is c! hope this : )
