What are the laws of energy conversion?

Those would basically be the First and Second Laws of Thermodynamics. The First Law (energy conservation) states that the total energy can not be increased or decreased. The Second Law imposes some limitations about what conversions are possible.


What law of thermodynamics is unavailable for doing work?

"Unavailable for doing work" is related to the Second Law of Thermodynamics.


What is the principle of the law of thermodynamics that states "useful energy in, useful energy out"?

The principle you are referring to is the second law of thermodynamics, which states that in any energy conversion process, some energy is lost as waste heat, resulting in a decrease in the overall usefulness of the energy.


According to the second law of thermodynamics it is not possible to change heat completely into work with no other change taking place?

The second law of thermodynamics states that not all heat energy can be converted into work. Some heat will always be lost in the form of waste heat during energy conversion processes. This law is a fundamental principle that governs the efficiency of energy conversion systems.


What law of thermodynamics tracks 'quality' of energy?

second law

The fact that usable energy is always lost in an energy transfer is due to what 1 Newton's first law of motion 2 the second law of thermodynamics 3 Newton's second law of motion 4 the first l?

The fact that usable energy is always lost in an energy transfer is due to the second law of thermodynamics. This law states that entropy, or disorder, tends to increase over time in a closed system, leading to the loss of usable energy in the form of heat.


Which law of thermodynamics states that the heat engine cannot be completely efficient?

True


What is the maximum efficiency possible in an energy conversion process that isn't limited by the second law of thermodynamics?

1) Any physical process is subject to the Second Law. Assuming otherwise would not be a realistic description of our Universe. 2) The maximum possible efficiency is a factor of 1 (equivalent to 100%). If some energy is wasted, as is usually the case, the actual amount will be somewhat less.


What is universal law of energy?

There is no commonly accepted law by that name, as far as I know. Two important laws about energy are the First Law of Thermodynamics and the Second Law of Thermodynamics.


What is the need of the second law of thermodynamics?

Second law of thermodynamics used for prove of process reversibility, it provide the concept of system loss capability to perform work. Second law of thermodynamics is an effective tools to debunked pseudo-science in the field of perpetual energy (perpetual magnetic generator) and hoax energy saving scam.
