Second Law of Thermodynamics

Mr. Anderson explains the second law of thermodynamics, focusing on entropy as a measure of disorder. He distinguishes between reversible and irreversible processes, noting that entropy increases over time in a closed system. Through examples, he illustrates how entropy behaves in different scenarios, emphasizing that while entropy never decreases in a closed system, it can appear to decrease in open systems by increasing disorder in the surroundings.

What does the second law of thermodynamics primarily deal with?

• Heat transfer

• Motion and force

• Entropy and disorder

• Energy conservation

In a reversible process, what happens to the entropy?

• It increases

• It decreases

• It remains unchanged

• It fluctuates randomly

Which of the following is an example of an irreversible process?

• A pendulum swinging

• A planet orbiting the sun

• Ice melting in a warm room

• A perfectly elastic collision

What happens to entropy in a closed system over time?

• It remains constant

• It decreases

• It increases

• It becomes zero

How can ordered systems like computers exist if entropy always increases?

• They are exceptions to the second law

• They decrease entropy in the universe

• They do not follow physical laws

• They increase entropy in their surroundings
