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).

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


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


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



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.


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.


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.


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


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.


That is a consequence of the second and third laws of thermodynamics.


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.


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.


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.


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.


The question has a problem - Newton stated laws of MOTION, not laws of Thermodynamics.Newton's Second Law of MOTION states:"In an inertial reference frame, the sum of the Forces Fon an object is equal to the mass m of that object multiplied by the acceleration a of the object (F = ma)."


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


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.


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.


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


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.


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").


1. You do not talk about thermodynamics 2. You DO NOT TALK about thermodynamics 3. One fire at a time 4. Fires will go on as long as they have to 5. If this is your first night, you have to fire


They don't. Breaking any of said laws is by definition impossible.


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.


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.]
