By the first law of thermodynamics, energy is conserved - i.e. the sum of the useful work and the energy lost to heat will equal the energy you started with.

The second law states that you will never get 100% energy efficiency.

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.


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 second law of thermodynamics.


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.


First and second laws of thermodynamics?

First Law of Thermodynamics: Energy can be converted from one form to another, but cannot be created or destroyed.Second Law of Thermodynamics: The second law of thermodynamics states that for any process occurring in a closed system, the entropy increases for an irreversible system and remains constant for a reversible system, but never decreases.


How does the second law of thermodynamics relate to how energy is passed on through the food chain?

The second law of thermodynamics states that as more chemical reactions occur, more heat energy is released in to the atmosphere. Apparently, heat energy is useless and so as more energy is transformed into heat energy, more entropy (or instability in the overall universe) becomes prevalent. So as energy is being consumed and passed up the food chain, chemical reactions to digest the food occurs and , as a result, entropy increases.

What law of thermodynamics accounts for the other 75 units of energy?

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.

Can the second law of thermodynamics be applied to anything other than food?

The Second Law of Thermodynamics applies to all processes in our Universe. It is not restricted specifically to food. In any process, the amount of unusable energy will increase. In extreme cases it might remain unchanged, but this is rather unlikely, since this implies 100% efficiency.


How do the first and second Laws of Thermodynamics relate to cellular metabolism?

Quite simply, just like anything else, cells need energy to work. The energy can't be created out of nothing (First Law), and usable energy gets converted to unusable energy, therefore new energy sources must be found (Second Law).


What law of thermodynamics says everything is running down?

The second law of thermodynamics states that a system with no energy input and no energy losses will tend toward dissolution.


How is the law of conservation of energy related to efficiency?

Efficiency can never be greater than one because it is the ratio between work you got out of the system and the total energy. Because of conservation of energy, the equation ΔE = Q + W reduces to Q + W = 0.
