Would nuclear fusion break the laws of thermodynamics?
No, nuclear fusion does not violate the laws of thermodynamics. It is a process that involves combining small atomic nuclei to form a heavier nucleus, releasing energy in the process. This energy release is consistent with the principles of thermodynamics.
Why pmm2 is impossible in thermodynamics?
A perpetual motion machine of the second kind (PMM2) is impossible according to the second law of thermodynamics, which states that heat cannot spontaneously flow from a colder body to a hotter body without external work. PMM2 would violate this principle by converting thermal energy from a heat reservoir into work without any loss, effectively creating energy from nothing. This contradicts the concept of entropy, which dictates that in any energy exchange, the total entropy of a system and its surroundings will either increase or remain constant, but never decrease. Thus, such a machine cannot exist.
How perpetual motion device can break the first and second law of the thermodynamics?
It can't. That's the simplest way to explain why no successful perpetual motion machine has ever been built. --------------------------------------------------------------- Another contributor persisted: well it's just a matter of time and life!
What law of thermodynamics explains the fact that if you drop an egg the shell will not spontaneously?
The second law of thermodynamics, which states that the total entropy of an isolated system can never decrease, explains why an egg does not spontaneously reassemble when dropped and broken. The disorder or entropy of the system increases when the eggshell breaks, making it energetically unfavorable for the pieces to reassemble on their own. Additional energy input would be required to reverse this process.
What two theories contradict the second law of thermodynamics?
Like all physical laws, the second law applies with a few restrictions. If you ignore those restrictions, you can come up with apparent violations. But you're misapplying the law, not contradicting it.Some people say the theory of evolution contradicts the second law because it posits an increase in order over time. That's silly for three reasons-Evolution theory does not posit an increase in order- it isn't necessarily true that more complex forms evolve from less complex ones.Entropy has everything to do with probability, and not much to do with "order" per se.Even if 1 and 2 weren't true, you have to consider both the system and the surroundings in applying the second law. For example, making a baby from raw materials would seem to be a tremendous decrease in entropy, so babies might "violate" the second law. But consider the baby's effect on the universe around it, too- the surroundings experience an even greater increase in entropy during baby-making (food is broken down and wastes are produced) and the net entropy change for the universe is positive.
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.
Are black objects better emitters of heat than white objects?
Yes. It has to be so, since it would otherwise be possible to violate the Second Law of Thermodynamics!
Why can't the pressure of seawater at different depths generate electricity?
Quite simply, that would violate the First Law of Thermodynamics, or the Second Law of Thermodynamics. The pressure difference is caused by the weight of the water above it, and it is an equilibrium situation.
Is death inevitable?
Yes. To live forever would violate the laws of thermodynamics. The only way not to would be to have no changes, which would not be living.
What is perpatual motion?
It is the idea of a machine continuously producing energy, without energy input - or producing more energy than what is put into the machine. This would violate the First Law of Thermodynamics (conservation of energy), and in general, it is not believed to be possible. No process is known which violates the conservation of energy. (A "perpetual motion machine of the second kind" would violate the Second Law of Thermodynamics; this is generally believed to be impossible, too.)
As water spontaneously freeze at room temperature the floor becomes very slightly cooler which law of thermodynamics has been violated?
That would significantly violate the second law of thermodynamics. For water to spontaneously freeze at room temperature, there would have to be something colder than the freezing point to absorb the energy coming out of the water. If the floor also became cooler, then it could not be absorbing energy. If you had ONLY the water and the floor, then this would also violate the 1st law - conservation of energy.
What is a violation of the first law of thermodynamics?
A cup of coffee cools down in a room cooler than it.but the reverse.. A cup of coffee heating up in a room cooler that it because of heat transfer from the air satisfies the first and violates the second.
Would nuclear fusion break the laws of thermodynamics?
No, nuclear fusion does not violate the laws of thermodynamics. It is a process that involves combining small atomic nuclei to form a heavier nucleus, releasing energy in the process. This energy release is consistent with the principles of thermodynamics.
Two identical blocks of iron one at 10c and the other at 20c are put in contact suppose the cooler bloock cools to 5c and the warmer block warms to 25c this would violate?
the second law of thermodynamics, which states that heat flows from a hotter object to a cooler object until thermal equilibrium is reached. In this scenario, the heat transfer would have to be from the warmer block to the cooler block, which contradicts the natural direction of heat flow without external intervention.
Why is a perpetual motion machine not possible?
It's not possible because it would violate one or both of the laws of thermodynamics. The first law of thermodynamics says that you can't create energy from nothing, or to out it another way, you can't get more energy out of a machine than you put into it. The second law says that no machine is 100% efficient. You must actually get less energy out of a machine than you put into it. The laws of thermodynamics apply to the entire universe and all bodies within it, including alleged perpetual motion machines.
What is the significance of the reversal of the second law of thermodynamics in the context of entropy?
The reversal of the second law of thermodynamics would mean that entropy, which tends to increase in a closed system, would instead decrease. This would have significant implications for the behavior of energy and matter in the universe, potentially allowing for processes that are currently considered impossible.
Is forbidden based on the second law of thermodynamics?
It forbids heat to move from a cold region to a hot regions spontaneously (you have to "pump" it there - meaning you have to do work to get it to move that direction). Alternatively - it forbids any natural/spontaneous process to DECREASE the entropy of the universe.
