Chapter 15, Problem 22Q

To determine

Is it a violation of second law of thermodynamics as the living organism when grow convert simple molecules into relatively complex structure?

Answer to Problem 22Q

Solution:

No, there is no violation of second law of thermodynamics as the living organism grows convert simple molecules into relatively complex structure.

Explanation of Solution

When living organism grows, the simple molecules converted into complex structure. This conversion of simple molecules into complex structure molecules includes the decrease in the entropy of the molecules because now they are more arranged and structured but this process does not occur spontaneously or in isolation. The growth of living organism is a part of environment and the entropy of the “living organism and environment” increases which is much larger than the decrease in the entropy of the molecules. So overall entropy of the universe is increased hence the of the second law of thermodynamic has been satisfied.
