How will the universe move toward entropy?
Actually its a bit Controversial, when we say Entropy, alot of things come into picture. So U just can't say Entropy is increasing. But in accordance with 2nd law of thermodynamics, it is true. U have to consider a particular system and its surroundings, then study its stability and Entropy.
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.
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.
When scientists say that entropy is always increasing what do they mean?
that obama is the worst prez ever.
What does the 2nd Law of Thermodynamics say about Direction of heat transfer?
In nature heat only moves naturally from warmer systems to cooler systems. One direction only. Never naturally from something cold into something hot. We can pump heat out of a system by doing work on it, such as a refrigerator where the refrigerant is compressed - making it much hotter than the surroundings - then letting it give off heat to the surroundings, then expanding it across a valve where the evaporation and expansion causes it to get colder than the inside of the fridge - then allowing it to absorb heat from the inside of the fridge, then sending it back to the compressor to start all over again.
What does the second law of thermodynamics say apex?
Energy cannot be created or destroyed.
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 a measure of how closely packed together the particles of matter are?
Perhaps you could say that entropy is a measure of this property.
When Energy Is Used Is It Gone Forever?
If it is an isolated system, then according to the second law of thermodynamics, it should decrease its entropy and continues to reach a thermal equilibrium. Energy is never lost nor created, so no, heat is not the final stage of energy that is wrong. The universe too will one day reach to its maximum entropy and there will no longer be any free energy for matter to interact with to perform work. But the energy of the universe will always remain the same. It is the disorderly of different energy states that allows free energy to be harnessed, for example, two adjacent rooms with a door in the middle having different temperature, the other being hotter while the other is colder, the moment the door is opened, hot air from the room will move to the colder room as what we observe as wind, that motion of air particles from hot to cold is free energy which can be used to perform work. Overtime, the temperature of the two rooms will equalize and there will no longer be any free energy to use. Say, at the beginning they have a room temperature of 30 C and 20 C, they have a difference of 10 C, therefore they are not a their thermal equilibrium, overtime they will settle to a final temperature (25 C) to follow the second law. The universe at its infancy was in a thermodynamic equilibrium, but because of quantum fluctuations, some areas had more matter than the other, causing an imbalance in the gravitational forces allowing the entropy of the universe to decrease, overtime the entropy of the universe will (or might have) reach minimum and will eventually increase as the system balances itself to a thermal equilibrium.
Who has higher entropy unopened playing cards or cooked spaghetti?
Entropy is tendency to be random. Unopened playing cards are pretty much set in their place, cooked spaghetti is all over the place in no set order. Thus, I would say cooked spaghetti would have higher entropy because it is the most random.
Can sound power a house with sound?
No. See the first law of thermodynamics, which states that the change in the internal energy of a closed thermodynamic system is equal to the sum of the amount of heat energy supplied to or removed from the system and the work done on or by the system or we can say " In an isolated system the heat is constant".
Is ice melting an example of thermal energy?
Ummm . . . let's just say that thermal energy is used to melt ice.
