# Which of the following is the best description of the second law of thermodynamics? (2023)

## Which of the following is the best description of the second law of thermodynamics?

The second law of thermodynamics is related to entropy. It states that the total entropy of the universe (system + surroundings) must increase in every spontaneous process. This statement is justified by option (c) When an isolated system undergoes a spontaneous change, the entropy of the system will increase.

Which of the following best describes the second law of thermodynamics?

The second law of thermodynamics states that whenever energy is remodeled, there's a loss of energy through the discharge of heat.

What is the second law of thermodynamics answers?

The second law of thermodynamics states that the total entropy can never decrease over time for an isolated system, that is, a system in which neither energy nor matter can enter nor leave.

What is the second law of thermodynamics?

The second law of thermodynamics asserts that heat cannot move from a reservoir of lower temperature to a reservoir of higher temperature in a cyclic process.

What is the 2nd law of Thermodynamics quizlet?

The second law of thermodynamics states that the total entropy can only increase over time for an isolated system, meaning a system which neither energy nor matter can enter or leave.

What is the best example of the second law of thermodynamics quizlet?

What is the best example of the Second law of Thermodynamics: Water flowing over a dam used to generate electricity.

Which best describes the law of thermodynamics?

So, the correct option is 'Energy is neither created nor destroyed, but it can change from one energy form to another'.

What is first second law of thermodynamics?

Two fundamental concepts govern energy as it relates to living organisms: the First Law of Thermodynamics states that total energy in a closed system is neither lost nor gained — it is only transformed. The Second Law of Thermodynamics states that entropy constantly increases in a closed system.

Why is the second law of thermodynamics important?

Why is the second law of thermodynamics so important? Second law of thermodynamics is very important because it talks about entropy and as we have discussed, 'entropy dictates whether or not a process or a reaction is going to be spontaneous'.

What is a real life example of the second law of thermodynamics?

Real life Example of second law of thermodynamics is that: When we put an ice cube in a cup with water at room temperature. The water releases off heat and the ice cube melts. Hence, the entropy of water decreases.

## What are the 1st 2nd and 3rd laws of thermodynamics?

1st Law of Thermodynamics - Energy cannot be created or destroyed. 2nd Law of Thermodynamics - For a spontaneous process, the entropy of the universe increases. 3rd Law of Thermodynamics - A perfect crystal at zero Kelvin has zero entropy.
