In our model for this class, there are 3 major stages to the System Life Cycle, each with 3 phases. What is the second phase of the second stage?

Choose the correct statement that supports the second law of thermodynamics.

1. The second law of thermodynamics is a principle that demonstrates the conservation of energy

2. The second law states that energy always degrades quality-wise

3. According to this, the entropy of an isolated system may decrease or increase

4. This law states that the flow of energy can take place in any direction naturally

Explain why the second law of thermodynamics is considered as the directional law of heat transfer?

Among the following statements, which statement finds the logical consequence of the second law of thermodynamics?

1. This law states that the entropy of an isolated system always increases or equal to zero but can never decrease

2. This law is a relationship between the energy and the internal energy of a system

3. This law states that entropy attains a constant value at absolute zero temperature

4. This law states enthalpy of a closed system is a point function
