Test: 2nd and 3rd Law of Thermodynamics and Entropy - Chemistry MCQ

For an isolated system with no exchange of energy with environment Q=0 and also dS>=dQ / T.

The net effect of an irreversible process is an increase in entropy of the entire system.

If an isolated system’s entropy differs from some parameter, then that parameter has a certain value that maximizes the entropy.

These are some general applications of the entropy principle.

Third law of thermodynamics was expressed by Nernst and it states that entropy of a system at absolute zero remains constant.

The second law of thermodynamics, which states that the entropy of an isolated system not in equilibrium will tend to increase over time, approaching a maximum value at equilibrium. According to this law, the entropy of an isolated system can indeed never decrease; it will either increase or remain constant if the system is undergoing a reversible process.

Therefore, the correct answer is: True

Clausius gave these two statements.

This is an overall fact about the entropy principle.

(T1+T2)/2 is when no work is done, and sqrt(T1*T2) is the temperature with maximum work distribution.

Third law of thermodynamics was expressed by Nernst and it states that entropy of a system at absolute zero remains constant.
