What is the difference between usable energy and the total amount energy?

What is the difference between usable energy and total energy?

Usable energy refers to the energy that can be effectively converted and utilized for various purposes, while total energy represents the sum of all energy present within a system, including both usable and unusable forms. Usable energy can be harnessed to perform work, whereas total energy includes potential energy that may not be readily available for use.

Why is the final amount of usable energy in an energy transformation less than the original amount?

The idea here is that part of the original energy is wasted - converted to an unusable type of energy.

The total amount of usable energy tends to increase in a closed system?

No. It tends to decrease.

What happens to usable energy?

In any transfer of energy or conversion of energy from one form to another, the total amount of energy does not change. The total amount of usable energy, however, always decreases.

Why the first and second law of thermodynamics may be states you can not get ahead and you can not break even?

According to the second law of Thermodynamics, the amount of usable energy will continuously decrease.According to the second law of Thermodynamics, the amount of usable energy will continuously decrease.According to the second law of Thermodynamics, the amount of usable energy will continuously decrease.According to the second law of Thermodynamics, the amount of usable energy will continuously decrease.

What is the difference between back pressure and absolute pressure in steam turbine?

Back pressure is the small amount of vacuum that is created when the used steam condenses from the turbine back into re-usable water.

Does the second Law of Thermodynamics contradict the First Law?

Not at all. The First Law states that energy is conserved - you can't create energy out of nothing, or make it disappear. The Second Law distinguishes usable from unusable energy, and states that the amount of unusable energy will increase over time - but the total (usable plus unusable energy) will still remain constant.Not at all.

What is the suns usable energy measured in?

The usable energy from the sun is typically measured in kilowatt-hours (kWh) or watts (W) for solar panels and systems. This helps to quantify the amount of energy that can be harnessed from the sun for various applications, such as generating electricity or heating water.

What is the usable energy called?

Usable energy is called kinetic energy, which is the energy possessed by an object due to its motion. It can be harnessed to perform work or activities.

Of the total amount of water on earth what is usable?

Any freshwater on Earth is usable

What does wasted energy add too?

Wasted energy will increase the amount of useless, or unusable, energy, and reduce the amount of usable energy in the Universe. The wasted energy is related to entropy - one way to express the Second Law of Thermodynamics is to say that there are irreversible processes (in terms of energy), another is that "entropy increases". However, entropy is not energy; it is not measured in Joule, but in Joule/Kelvin. In any case, you might say that when energy is wasted, entropy increases.Wasted energy will increase the amount of useless, or unusable, energy, and reduce the amount of usable energy in the Universe.

What are the comparison of energy output with energy input?

Energy output refers to the amount of usable energy obtained from a system, while energy input is the amount of energy required to operate that system. A system is considered efficient when the energy output is greater than the energy input. Conversely, inefficiency occurs when more energy is put into a system than what is obtained as output.
