Correct Answer: C
Topic: Concept 8.1
Skill: Knowledge/Comprehension
3) Which of the following is a statement of the first law of thermodynamics?
A) Energy cannot be created or destroyed.
B) The entropy of the universe is decreasing.
C) The entropy of the universe is constant.
D) Kinetic energy is stored energy that results from the specific arrangement of matter.
E) Energy cannot be transferred or transformed.
Correct Answer: A
Topic: Concept 8.1
Skill: Knowledge/Comprehension
4) For living organisms, which of the following is an important consequence of the first law of thermodynamics?
A) The energy content of an organism is constant.
B) The organism ultimately must obtain all of the necessary energy for life from its environment.
C) The entropy of an organism decreases with time as the organism grows in complexity.

, 5) Living organisms increase in complexity as they grow, resulting in a decrease in the entropy of an organism.
How does this relate to the second law of thermodynamics?
A) Living organisms do not obey the second law of thermodynamics, which states that entropy must
increase with time.
B) Life obeys the second law of thermodynamics because the decrease in entropy as the organism grows is
balanced by an increase in the entropy of the universe.
C) Living organisms do not follow the laws of thermodynamics.
D) As a consequence of growing, organisms create more disorder in their environment than the decrease in
entropy associated with their growth.
E) Living organisms are able to transform energy into entropy.
Correct Answer: D
Topic: Concept 8.1
Skill: Synthesis/Evaluation
6) Whenever energy is transformed, there is always an increase in the
A) Free energy of the system.
B) Free energy of the universe.
C) Entropy of the system.
D) Entropy of the universe.
E) Enthalpy of the universe.
Correct Answer: D
Topic: Concept 8.1
Skill: Knowledge/Comprehension
7) Which of the following statements is a logical consequence of the second law of thermodynamics?
A) If the entropy of a system increases, there must be a corresponding decrease in the entropy of the
universe.
B) If there is an increase in the energy of a system, there must be a corresponding decrease in the energy of
the rest of the universe.
C) Every energy transfer requires activation energy from the environment.
D) Every chemical reaction must increase the total entropy of the universe.
E) Energy can be transferred or transformed, but it cannot be created or destroyed.
Correct Answer: D
Topic: Concept 8.1
Skill: Synthesis/Evaluation
8) Which of the following statements is representative of the second law of thermodynamics?
A) Conversion of energy from one form to another is always accompanied by some gain of free energy.
B) Heat represents a form of energy that can be used by most organisms to do work.
C) Without an input of energy, organisms would tend toward decreasing entropy.
