According to the first law of thermodynamics, what happens to energy?

• It can be created

• It can be destroyed

• It is conserved

• It is multiplied

In the context of the first law, what does a positive 'q' indicate?

• Heat is lost by the system

• Work is done on the system

• Work is done by the system

• Heat is gained by the system

What defines a spontaneous process according to the second law of thermodynamics?

• A process that is reversible

• A process that decreases entropy

• A process that requires energy input

• A process that occurs naturally without external work

How is entropy related to randomness or disorder?

• Entropy decreases with increased randomness

• Entropy increases with increased randomness

• Entropy is the opposite of randomness

• Entropy is unrelated to randomness

Which statement correctly describes the entropy change in a spontaneous process?

• Entropy of the universe increases

• Entropy of the system always increases

• Entropy of the universe remains constant

• Entropy of the universe decreases

What must be true for the sum of the entropy changes of the system and surroundings in a spontaneous process?

• It must be equal to the system's entropy change

• It must be positive

• It must be negative

• It must be zero

What does the third law of thermodynamics state about a perfect crystal at absolute zero?

• It has undefined entropy

• It has infinite entropy

• It has zero entropy

• It has maximum entropy

How does temperature affect entropy according to the third law?

• Entropy decreases as temperature increases

• Entropy remains constant with temperature change

• Entropy increases as temperature increases

• Entropy is unaffected by temperature

What is the significance of absolute zero in the context of entropy?

• It is the point of undefined entropy

• It is the point of zero entropy

• It is the point of infinite entropy

• It is the point of maximum entropy
