Does a truck crashing into a wall demonstrates the second law of thermodynamics?
If pieces of the truck fly off then yes, if all the parts manage to stick together then no. I would have to say that this is not a good example of the 2nd law.
What does the 1st Law of Thermodynamics say about the possibility of unscrambling eggs?
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.
What is the first law of thermodynamics known as?
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 .
Why zero law of thermodynamics is called as zero law?
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.
Law that states that energy cannot be created or destroyed?
The law of Conservation of Energy. Actually, that law has been superceded now by a slightly different one. Recently (maybe 100 years ago) it was learned that energy can become mass and mass can become energy. So the law had to be modified to say that the total combination of mass and energy can't be created or destroyed.

Has science succeeded in proving the first law of thermodynamics?
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.
What does wasted energy add too?
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.

What is the best interpretation of the first law of thermodynamics?
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.

Explain the second law of thermodynamics and explain why it is not violated by living organisms?
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.
If energy cant be created or destroyed why are we concerned about running out of energy?
There are TWO important laws about energy; you need to understand them both. They are known as the laws of thermodynamics. Actually there are a few more, but the first and second laws are extremely important to understand this question. If you ONLY understand the first one, you will only get an incomplete picture.* First Law of Thermodynamics: This is basically conservation of energy. * Second Law of Thermodynamics: This can be expressed in many different ways; as a simple introduction, let's just say that useful energy can - and will - convert into unusable energy. This happens all the time, and is unavoidable. For example, once a car uses up its fuel, the energy that was originally in the fuel is still out there somewhere, but in a "less concentrated", and utterly unusable, form. Among other things, the tires and the road have been heated up a bit.
The only reactants in a reaction were Zn and HCI. What does the law of conservation of matter say about the products?
The product will contain only Zn, H, and CI. -Apex
