"Unavailable for doing work" is related to the Second Law of Thermodynamics.
Yes, according to the Second Law of Thermodynamics, the total energy in the universe is becoming increasingly unavailable for doing work. This is because energy tends to disperse and become more evenly distributed over time, leading to a decrease in the amount of energy available to do useful work.
The work of Sadi Carnot, a French engineer, on the efficiency of heat engines in the early 19th century led to the formulation of the second law of thermodynamics. Carnot's insights on the limitations of heat engine efficiency laid the foundation for the development of the second law, which eventually became a fundamental principle in thermodynamics.
The way that the question is worded it is impossible to be sure exactly what you are looking for, but as a reasonable guess, you are looking for what happens to energy that is not producing useful work. The second law of thermodynamics generally tells us that we can never get 100% efficiency, i.e. we can never convert all the energy we are using into useful work. Some of the energy will just go into increasing the entropy of the universe.
Second Law of Thermodynamics
That would be the First Law of Thermodynamics
Yes, according to the Second Law of Thermodynamics, the total energy in the universe is becoming increasingly unavailable for doing work. This is because energy tends to disperse and become more evenly distributed over time, leading to a decrease in the amount of energy available to do useful work.
The second law does not allow complete conversion of heat into work.
Entropy is a measure of disorder or randomness in a system. In the context of thermodynamics and the second law of thermodynamics, entropy tends to increase over time in isolated systems. This means that energy tends to disperse and become less organized, leading to a decrease in the system's ability to do work. The second law of thermodynamics states that the total entropy of a closed system will always increase or remain constant, but never decrease.
True
Not exactly. The first law of thermodynamics, i.e. the law of conservation of energy, also accounts for heat as one of the many forms that energy can take. There is no one law called "the law of thermodynamics", but there are several "Laws of Thermodynamics" (note the plural form "LAWS").
Thermodynamic cycle is based on 2nd law of thermodynamics.
Magic
The 1st Law of thermodynamics is a restatement of the law of conservation of energy.
In many energy transformations, there is an increase in the amount of disorder or randomness in the system, known as entropy, as dictated by the second law of thermodynamics. This means that some energy becomes unavailable to do work, leading to a loss of usable energy in the process.
The work of Sadi Carnot, a French engineer, on the efficiency of heat engines in the early 19th century led to the formulation of the second law of thermodynamics. Carnot's insights on the limitations of heat engine efficiency laid the foundation for the development of the second law, which eventually became a fundamental principle in thermodynamics.
The first law of thermodynamics is also known as the Law of Energy Conservation.
James Prescott Joule, a 19th-century physicist, had an exceptional reputation for his work in the field of thermodynamics. His most notable contribution is the discovery of the first law of thermodynamics, also known as the law of conservation of energy. Additionally, Joule's experiments on the relationship between mechanical work and heat laid the foundation for the science of thermodynamics.
