Question

Give any two statements of the second law of thermodynamics.

Answer 1

Answer:

ll Law of Thermodynamics:

Kelvin Statement:

No process is possible whose sole result is the absorption of heat and complete conversion into work.

Clausius Statement:

No process is possible whose result is the transfer of heat from cold body to hot body without any external heat.

Answer 2

Answer:

According to the second law of thermodynamics, any spontaneously occurring process will always result in an increase in the universe's entropy (S). In simple terms, the law states that the entropy of an isolated system will never decrease over time.

Explanation:

The following are some statements about the second law of thermodynamics:

• Plank Kelvin Statement: If a heat engine simply exchanges heat with bodies at a single fixed temperature, it is impossible for it to build a network in a complete cycle.
• Clausius's Theorem: It is difficult for a machine to transmit heat from a cold body to a hot body without exerting some effort.
• Entropy statement:  A process accompanied by an increase in entropy tends to be spontaneous.
