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.

Because of conservation of energy (together with the Second Law of Thermodynamics), the output energy can't be greater than the input energy; the efficiency can't be greater than 1 (i.e., 100%).

What law of the scientific rule states that energy cannot be created or destroyed?
The law of Conversation of Energy
What chemical equations violates the law of conservation of energy?
Any chemical equations violates the law of conservation of energy.
How are the law of conservation of enegry and the law of mass similar?
The Law of conservation of Energy applies to mass as mass is a form of energy, E=mc2.
How The Law of Conservation of Energy Applies To Energy?
in closed systems
What does the law of conservation state?
The law of conservation states that energy can neither be created or destroyed but can be found existing in different forms
How are energy transformation related to the law of conservation of energy?
o
What law says a machine cant give 110 percent efficiency?
The Law of Conservation of Energy, also known as the First Law of Thermodynamics.
What the different between the law of conservation of energy and conserving energy?
The law of conservation of energy states that the total energy in the universe is a constant and will remain so for example ( x=y+z ). conservation of energy has to do with reducing the amount of energy used through reduced activity and/or increased efficiency in the performance of a particular task.
How are energy transformations related to law of conservation of energy?
it changes forms and energy can not be created or destroyed
The first law of thermodynamics is related to the conservation of which quantity?
Yes. There are no known exceptions - otherwise it would not be considered a law
What law of the scientific rule states that energy cannot be created or destroyed?
The law of Conversation of Energy
What law says in chemical change energy is neither created or destroyed?
Scientists call this law the law of conservation of matter
How is the 1st law of thermodynamics related to the conservation of energy?
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.
Law that states that energy cannot be created or destroyed?
The law of Conservation of Energy. Actually, that law has been superceded now by a slightly different one. Recently (maybe 100 years ago) it was learned that energy can become mass and mass can become energy. So the law had to be modified to say that the total combination of mass and energy can't be created or destroyed.
What law of thermodynamics states that different forms of energy can be converted into one another?
That's related to the First Law of Thermodynamics - the Law of Conservation of Energy.
The first law of thermodynamics which is closely related to the law of conservation of energy states that?
energy can be transformed in different ways but can never be created or destroyed.
Of thermodynamics is a restatement of the law of conservation?
The 1st Law of thermodynamics is a restatement of the law of conservation of energy.
