Thermodynamics

Question 1

What is the first law of thermodynamics?

Answer 1

The first law of thermodynamics states that energy cannot be created or destroyed, only transformed from one form to another.

Question 2

True or False: The second law of thermodynamics implies that energy transformations are 100% efficient.

Answer 2

False

Question 3

Fill in the blank: The ______ law of thermodynamics states that the entropy of an isolated system always increases over time.

Answer 3

second

Question 4

What does the third law of thermodynamics state about absolute zero?

Answer 4

The third law of thermodynamics states that as the temperature approaches absolute zero, the entropy of a perfect crystal approaches zero.

Question 5

Which law of thermodynamics is concerned with the conversion of heat into work?

Answer 5

The first law of thermodynamics.

Question 6

Multiple choice: Which of the following is a consequence of the second law of thermodynamics? A) Energy conservation B) Entropy increase C) Heat transfer D) All of the above

Answer 6

B) Entropy increase

Question 7

Short answer: Define entropy in the context of thermodynamics.

Answer 7

Entropy is a measure of the disorder or randomness in a system.

Question 8

True or False: The first law of thermodynamics can be expressed mathematically as ΔU = Q - W.

Answer 8

True

Question 9

What is a thermodynamic system?

Answer 9

A thermodynamic system is a defined quantity of matter or a region in space chosen for analysis.

Answer 10

third
