Question

The second law of thermodynamics states that:
A. All spontaneous processes are thermodynamically irreversible
B. Entropy of the universe is continuously increasing
C. Energy can neither be created nor be destroyed
D. Energy of the universe remains constant

Answer 1

Hint:
Energy exists in many forms, such as heat, light, chemical energy and electrical energy. Energy is the ability to conduct change or to do work. Thermodynamics is the study of energy. This law is introduced to isolated systems only, and the earth is not an isolated system or closed system.

Complete step by step solution:
The Second Law of Thermodynamics expresses that the condition of entropy of the whole universe, as a disengaged framework, will consistently increment after some time. The subsequent law likewise expresses that the adjustments in the entropy known to mankind can never be negative.

Option A: The second law of thermodynamics manages the heading taken by spontaneous processes. Numerous processes happen suddenly one way just—that is, they are irreversible, under a given arrangement of conditions. Despite the fact that irreversibility is found in everyday life—a wrecked glass doesn't continue its unique state, for example—complete irreversibility is a measurable explanation that can't be seen during the lifetime of the universe. All the more decisively, an irreversible cycle is one that relies upon way. On the off chance that the cycle can go just a single way, at that point the converse way varies essentially and the cycle can't be reversible.

Option B: The second law can be stated that “all the spontaneous processes produce an increase in the entropy of the universe”.

Option C: First Law of Thermodynamics: Energy can be changed starting with one structure then onto the next, however it can't be made or decimated. The aggregate sum of energy and matter in the Universe stays steady, just changing starting with one structure then onto the next. The First Law of Thermodynamics (Conservation) expresses that energy is constantly preserved, it can't be made or annihilated. Fundamentally, energy can be changed over from one structure into another.

Option D: The law of conservation of energy, also known as the first law of thermodynamics, states that the energy of a closed system must remain the same —it can neither increase nor decrease without the disturbance from outside.
Hence, The second law of thermodynamics states that entropy of the universe is continuously increasing and is irreversible.

The correct options are A & B

Note:
A few critics guarantee that development violates the Second Law of Thermodynamics, since association and intricacy increments in advancement. Notwithstanding, this law is alluding to disengaged frameworks just, and the earth isn't a secluded framework or shut framework.
