The first law of thermodynamics is: Energy cannot be made or destroyed. But heat energy can be used to power movement energy, and movement energy can turn into heat energy.

The second law of thermodynamics is: Heat energy always moves from hot things to cold things (this is why the sun will heat up cold lemonade if the lemonade is left outside on a hot day).

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 many thermodynamics laws are there?

Basically four: the zeroeth law, the first law, the second law and the third law.


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.


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.


Which law of thermodynamics states that the heat engine cannot be completely efficient?

That is a consequence of the second and third 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 is the constraints of energy?

The usual constraints are the First and Second Laws of Thermodynamics: First: energy is conserved; and second: useful energy gets converted into unusable energy - not the other way round.


What are the laws of energy conversion?

Those would basically be the First and Second Laws of Thermodynamics. The First Law (energy conservation) states that the total energy can not be increased or decreased. The Second Law imposes some limitations about what conversions are possible.


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.


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.


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.


Which of the laws of thermodynamics has exceptions?

None. The laws of thermodynamics describe physical phenomena. The first one is the same as "if you put a pan on a hot stove, it will get warmer." Such laws of physics simply describe reality.


Does living things always follow second law of thermodynamics?

Everything always follow laws of physics. If they weren't they wouldn't be laws.

When the law of conversation of energy is applied to heat it is known as the law of thermodynamics?

Not exactly. The first law of thermodynamics, i.e. the law of conservation of energy, also accounts for heat as one of the many forms that energy can take. There is no one law called "the law of thermodynamics", but there are several "Laws of Thermodynamics" (note the plural form "LAWS").


How many laws of thermodynamics are there?

Four


Why Zeroth law of thermodynamics is not called as 3 Rd law of thermodynamics though it was discovered after 1 and 2 law?

It was found to be more fundamental than the other laws. It should therefore be the first law, but at that time, renumbering all the laws was deemed impractical, since the terms "First Law" and "Second Law" were already well-established.


What isThermal energy moving from a warmer object to a cooler object is called what?

The second law of thermodynamics thermal transfer, energy conduction. Actually the first three laws of thermodynamics are all included in this rather simple phenomena. [The zeroth law, the first law, and the second law. The third law doesn't find application in this situation.]


Is the first law of thermodynamics is concerned with entropy?

No. The Second Law is concerned with entropy.
