Energy cannot be created or destroyed.
No, a truck crashing into a wall does not directly demonstrate the second law of thermodynamics. The second law deals with the flow of energy and the tendency of systems to increase in entropy over time, which are more related to processes like heat transfer and chemical reactions.
The first law of thermodynamics states that energy cannot be created or destroyed, only converted from one form to another. It is also known as the law of conservation of energy.
First law of thermodynamics doesn't really address unscrambling eggs. The second law, however, suggests that it would take an outside expenditure of energy and release of heat to the environment to "unscramble" eggs. The eggs would not unscramble themselves naturally. Of course, in case you haven't noticed, eggs do not scramble themselves naturally. It requires an outside action to cause them to become scrambled too.
The first and second laws were already formulated when the "zeroeth law" was suggested, however, the zero law is necessary in order to define the quantity "temperature" critical to the second law, so someone suggested just numbering it zero so that it would come before the already well established 1st and 2nd laws, rather than re-numbering them.
No. The second law still determines if a process will take place spontaneously. The first law does not say that if you drop a block of hot iron into a water bath that the iron can't absorb enough energy from the water to melt it while freezing the water as long as the energy absorbed by the iron matches the energy lost by the water. HOWEVER, the second law tells us this won't happen.

The first law of thermodynamics states that energy cannot be created or destroyed, only converted from one form to another. It is also known as the law of conservation of energy.
The law governing changes in energy is primarily encapsulated in the first law of thermodynamics, which states that energy cannot be created or destroyed, only transformed from one form to another. This means that when energy changes from, for example, kinetic to potential energy, the total energy in a closed system remains constant. Additionally, the second law of thermodynamics addresses the direction of these energy transformations, indicating that energy tends to disperse or spread out, leading to increased entropy in isolated systems.

The first law is also known as law of conservation of energy. It say that the energy can neither be created nor be destroyed but can only be transferred. Its is given by this equation dQ = dU + dW .
The law that states energy cannot be created or destroyed is the First Law of Thermodynamics. It is also known as the Law of Conservation of Energy, which states that energy can only change forms or be transferred from one system to another.
Wasted energy will increase the amount of useless, or unusable, energy, and reduce the amount of usable energy in the Universe. The wasted energy is related to entropy - one way to express the Second Law of Thermodynamics is to say that there are irreversible processes (in terms of energy), another is that "entropy increases". However, entropy is not energy; it is not measured in Joule, but in Joule/Kelvin. In any case, you might say that when energy is wasted, entropy increases.Wasted energy will increase the amount of useless, or unusable, energy, and reduce the amount of usable energy in the Universe.

The first law of thermodynamics says that energy can neither be created nor destroyed; it can only be changed from one form to another. One of the implications of this is that the total energy of the universe is finite. Einstein's famous equation E=mc**2 provides a corollary to the first law by demonstrating that mass and energy are interrelated. Since they are related by his equation, the first law could be modified to say that the combination of mass and energy is finite for the universe, or that matter is just another form of energy. When energy is converted to mass the increase in mass is usually so tiny that it is not detectable within experimental uncertainty but it can be calculated. The one exception to this is when high energy photons (e.g. gamma rays) convert to a matter-antimatter particle pair. However the antimatter particle so rapidly collides with a matter particle, converting back to a high energy photon that although easily detectable in experiments it has no practical value.

this increase in organization over time in no way violates the second law. The entropy of a particular system, such as an organism, may actually decrease, so long as the total entropy of the universe-the system plus its surroundings-increases. Thus, organisms are islands of low entropy in an increasingly random universe. The evolution of biological order is perfectly consistent with the laws of thermodynamics.
