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 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.

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.


According to the second law of thermodynamics no system can convert energy from one form to another useful form with 100 percent efficiency?

True


Why does the 2nd law of thermodynamics relate to the direction of heat flow and efficiency of heat engines?

Because Energy flow is from a high energy state to a low energy state the direction of flow of heat is from a high temperature to a low temperature. Because the second law states that no system can perfectly maintain it's total energy, the efficiency of a heat engine must necessarily be reduced by the entropy of the energy transfer.


How do the first and second law of thermodynamics relate to ecosystems?

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


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

That's highly fictional, because any real process IS limited by the Second Law.


How does the second law of thermodynamics relate to renewable energy?

Due to the second law of thermodynamics, even "renewable" energy yields a net release of heat to the surroundings. An advantage of renewable energy is that it can be a predictable, sustainable source of energy as opposed to fossil fuels extracted from the ground which apparently take millions of years to create through geological processes.


Can energy be regenerated?

According to the Second Law of Thermodynamics, once energy is wasted, it is gone forever - useful energy has become unusable energy.According to the Second Law of Thermodynamics, once energy is wasted, it is gone forever - useful energy has become unusable energy.According to the Second Law of Thermodynamics, once energy is wasted, it is gone forever - useful energy has become unusable energy.According to the Second Law of Thermodynamics, once energy is wasted, it is gone forever - useful energy has become unusable energy.


How efficient is solar energy?

The second law of thermodynamics forbids a 100%-efficient solar cell. The result is, for a system with sunlight concentration the maximum efficiency is ~85%, and for a system that does not track the sun, the maximum efficiency is ~55%.


Are formulations of the second law of thermodynamics?

What is a logical consequence of the second law of thermodynamics?

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.


Which Laws of Thermodynamics states that energy and matter cannot be created or destroyed?

The Second Law of Thermodynamics is equivalent to the Law of Conservation of Energy. The Law of Conservation of Matter is not stated in the laws of Thermodynamics.


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.


What law of thermodynamics states that heat is a natural by-product of most energy conversion processes?

This is related to the Second Law of Thermodynamics.

What is second law of themodynamics?

Law of thermodynamics deals with the heat energy involved in a reaction. According to second law of thermodynamics, the energy system tries to increase the entropy. The entropy is a measure of chaos of molecules.

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.


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 defines Second law of thermodynamics?

The Second Law of Thermodynamics states that "in all energy exchanges, if no energy enters or leaves the system, the potential energy of the state will always be less than that of the initial state." This is also commonly referred to as entropy.
