Which of the following statements is consistent with the second law of thermodynamics?
A) A gain of free energy in a system is always associated with conversion of energy from one form to another.
B) A constant input of energy is required to maintain the high level of cellular organization.
C) Without an input of energy, the entropy of an organism would tend to decrease over time.
D) Every energy transformation performed by an organism decreases the entropy of the universe.

Question

Quizplus · Accepted Answer

The second law of thermodynamics states that in any energy transfer or transformation, the total entropy of a closed system always increases over time. This means that to maintain a high level of organization in a system - such as a cell or organism - a constant input of energy is required, otherwise the system will become disordered and entropy will increase. A, C, and D are all inconsistent with the second law.
