The second law of thermodynamics says that entropy is conserved False. O True Submit Request Answer Part B If the entropy of the system increases during a reversible process, the entropy change of the surroundings must decrease by the same amount. False O True. Submit Request Answer PartC In a certain spontaneous process the system undergoes an entropy change of 4.2 J/K; therefore, the entropy change of the surroundings must be -4.2 J/K. True. O False Submit Request Answer

Explanation / Answer

Part A)

According to second law entropy is conserved

True

For a entire system and surrounding, that is universe the entropy remains same. The entroppy of the system and surrounding are opposite of each other but overall remains the same.

Part B)

If the entropy of system increases, entropy of surrounding must decrease,

True

the overall entropy is conserved. system is spontaneous and surrounding is non-spontaneous here

Part C)

In a spontaneous process If system entropy is 4.2 J/K. The surrounding entropy is -4.2 J/K

True

Same but opposite is sign.
