The first and second laws apply EVERYWHERE, including ecosystems. Specifically, living beings need energy - and that means, usable energy - to live.

How do the first and second laws of thermodynamics relate with to the law of conservation of energy?

As stated by the expert: The First Law of Thermodynamics IS the Law of Conservation of Energy. The Second Law of Thermodynamics is not directly related; however, it provides additional restrictions, as to what can, and what cannot, be achieved.


How does energy efficiency relate to the first and second law of thermodynamics?

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.


How many laws of thermodynamics?

There are four laws of thermodynamics;Zeroth Law of Thermodynamics.First Law of Thermodynamics.Second Law of Thermodynamics.Third Law of Thermodynamics.



Distinguish the first and second laws of thermodynamics in terms of whether or not exceptions occur?

There are hypothetical processes that would obey the First Law, but disobey the Second Law of Thermodynamics.


First and second law 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 do the first and second law of thermodynamics relate to ecosystems on earth?

The second law of thermodynamics can be related to entropy. This means "all natural systems left to their own devices will follow a path of decline or become unorganised".The reason this relates to ecosystems on earth is because if we do work on a system it can become more organised. Similar to if we were to do work on an object it would gain heat.The relation to the second law is that natural systems left to their own devices cannot become more organised. Just like heat cannot flow from cold to hot naturally.Comments: I've corrected some errors in that answer, but it's still a bit unusual and probably needs improving. For example living organismsobviously can become more organised.The second law is a bit tricky. Remember it applies to "closed systems". Open systems can be affected by "outside" things such as energy input.As regards the first law of thermodynamics, that's basically the law of conservation of energy.So, obviously, ecosystems need an energy source.


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 do the first and second laws of thermodynamics relate to?

First law tells that heat energy can be converted into equivalent amount of work,but it is silent about the conditions under which this conversion takes place.Tha second law is concerned with the cicumstances in which heat can be converted into work and direction of flow of heat.



What forces are used in sports?

Gravity, the First and Second Laws of Thermodynamics, etc.


Is the first law of thermodynamics is concerned with entropy?

No. The Second Law is concerned with entropy.



What is the first and second laws of Thermodynamics?

First Law of Thermodynamics is also known as Conservation of Energy. Second Law of Thermodynamics means that useful energy is continuously being converted into unusable energy - there are irreversible processes in our Universe, with respect to energy. Read the Wikipedia articles for a more thorough discussion.


Can you have a negative coefficient of kinetic friction?

Since this would make it possible to violate either the First Law of Thermodynamics or the Second Law of Thermodynamics, the answer is clearly NO.



Does a heat engine of efficiency 100 percent necessarily violate the first and second law of thermodynamics?

A heat engine of 100 percent efficiency violates the second law of thermodynamics and is impossible even in theory.


What are the first and second law of energy?

You must be referring to the two Laws of Thermodynamics. Stated in terms of energy: 1. The First Law of Thermodynamics is the Law of Conservation of Energy, meaning that energy can not be created or destroyed. 2. However, useful energy is continuously being converted into unusable energy. This is irreversible. This is the Second Law of Thermodynamics.


What is the difference between the first and secong law of thermodynamics?

The first law is about conservation of energy, the second is about the conservation of entropy.


Why can't electric suppliers use electric motors to spin the generators?

If you are suggesting a "perpetual motion" scenerio, it would violate the first or second laws of thermodynamics. Many inventors dream of perpetual motion machines, but they are an impossible dream according to the laws of thermodynamics. The second law of thermodynamics says that an engine or process of any type must always have an efficiency of less than 100%. A perpetual motion machine that uses a generator to power the motor that runs the generator requires both the generator and motor to operate with 100% efficiency. This type of perpetual motion machine does not violate the first law of thermodynamics, but violates the second law of thermodynamics. It is a perpetual motion machine of the second kind because it violates the second law of thermodynamics. Not even the cleverest engineer or inventor can build a perpetual motion machine because it would violate either the first or second law of thermodynamics, which are fundamental laws of physics.


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.


Is relate singular or plural?

The verb to relate can be used for a singular or a plural subject; for example:First person, singular: I relate the lines.First person, plural: We relate the lines.Second person, singular: You relate the lines.Second person, plural: You relate the lines.Third person, singular: He relates the lines. Shewill relate the lines.Third person, plural: They relate the lines.



Can energy be produced?

You can't create energy out of nothing (First Law of Thermodynamics); this is an experimentally established fact (i.e., no exceptions are known). Nowadays, the law of conservation of energy (or First Law of Thermodynamics) is often derived from Noether's Theorem, but that is some advanced math.You can convert one type of energy to another, but see also the Second Law of Thermodynamics.You can't create energy out of nothing (First Law of Thermodynamics); this is an experimentally established fact (i.e., no exceptions are known).
