Second Law of Thermodynamics

Post by seders99 » Wed Mar 11, 2009 10:57 pm

Which of the following statements is not representative of the second law of thermodynamics?

a. conversion of energy from one form to another is always accompanied by some loss of free energy
b. heat represents a form of energy that cannot be used by most organisms to do work
c. without an imput of energy, organisms would tend towards increasing entropy
d. cells require a constant input of energy to maintain their high level of organization
e. every energy transformation by a cell decreases the entropy of the universe

I know that the second law states in all energy exchanges, if no energy enters or leaves the system, the potential energy of the state will always be less than that of the initial state.

I think the answer is B

I think it's c. Organisms need to use energy to increase entropy. If they don't have energy, they can't increase entropy.
