The First Law is Conservation of Energy (stated in the language of Thermodynamics). Energy can neither be created nor destroyed.

The Second Law has many formulations; one of them is that entropy increases. Another is that there are irreversible processes in the Universe - irreversible in the sense of energy processes. In other words, useful energy is constantly being converted into unusable energy.

Is thermodynamics a law or theory?

Thermodynamics is both a law and a theory. It has a set of well-established laws, such as the first and second laws of thermodynamics, which describe the behavior of energy in systems. Additionally, the principles and concepts underlying thermodynamics are formulated into a theory to explain and predict the behavior of physical systems.


How many thermodynamics laws are there?

There are three laws of thermodynamics. The first law states that energy cannot be created or destroyed, only transformed. The second law states that heat naturally flows from hot to cold. The third law states that as temperature approaches absolute zero, the entropy of a perfect crystal approaches zero.


Two scientists who began the laws of thermodynamics?

Two scientists who are generally thought of as establishing the laws of thermodynamics are French physicist Nicolas Léonard Sadi Carnot who studied the efficiency of heat engines believing it was the key that could help France win the Napoleonic Wars and Scottish physicist Lord Kelvin who was was the first to formulate a concise definition of thermodynamics in 1854.


How do food webs illustrate the first and second laws of thermodynamics?

Food webs illustrate the first law of thermodynamics by showing the conservation of energy within an ecosystem - energy is transferred from one organism to another as they consume and are consumed. They also demonstrate the second law by showing that energy is lost as heat during these transfers, leading to a decrease in available energy at each trophic level.


How do the laws of thermodynamics support that the universe came from nothing?

They don't. What they do support is that the Universe must have had a beginning. This is because, according to the Second Law of Thermodynamics, there are irreversible processes in nature - the Universe can't remain the way it is forever.

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.

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 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.

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.


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.


How do plants break the second law of thermodynamics?

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