The entropy of the universe is increasing
The Second Law of Thermodynamics.
Entropy is closely related to the second law of thermodynamics, which states that the entropy of a closed system will always remain the same or increase over time, but never decrease. This law describes the tendency of systems to move towards a state of maximum disorder or randomness.
No; it would appear to be the result of misunderstanding the Second of Law of Thermodynamics (due to Clausius), which states that the entropy in a closed system increases. This does not prohibit the reduction of entropy (as in the evolution of complex life forms) in a limited space as long as it is balanced by a greater increase in entropy elsewhere. But more importantly, the Earth is not a closed system in the sense of thermodynamics: it receives radiant energy from the Sun, and loses heat to space. The quotation, by the way, is due to Roger Caillois, but it is hardly famous.
That depends on what you mean by "cold" system. Entropy in any system can do one of three things: increase, decrease, or remain constant. If the system is closed, then entropy will only ever increase. If the system is open, entropy within it can do any of the three, provided there is a corresponding change in entropy outside the system (energy must come from or go to somewhere to effect an entropy change). The absolute amount of energy in the system makes no difference to the entropy of it. It is whether you have an open or closed system that counts.
the second law of thermodynamics states that systems tend to change in a way that increases the disorder.
The second law of thermodynamics states that as more chemical reactions occur, more heat energy is released in to the atmosphere. Apparently, heat energy is useless and so as more energy is transformed into heat energy, more entropy (or instability in the overall universe) becomes prevalent. So as energy is being consumed and passed up the food chain, chemical reactions to digest the food occurs and , as a result, entropy increases.
The second law of thermodynamics states that entropy always increases with time. Based on this, the British astronomer, Arthur Eddington developed the concept of the "Arrow of Time". According to this time is asymmetrical and we can only go forward in time. As a result days cannot go back.
The vapoor stae of an elemnt has the greates entropy. Entropy is a state function in thermodynamics, and is sometime termed as measure of disorder. Another interpretation is that it is a measure of the spread of energy across micro-states. There ae more micro-states in a vapor, due to the quantization of rotation and vibration.
The Second Law of Thermodynamics states that "in all energy exchanges, if no energy enters or leaves the system, the potential energy of the state will always be less than that of the initial state." This is also commonly referred to as entropy.
the second law of thermodynamics states that systems tend to change in a way that increases the disorder.
The first law of thermodynamics states that energy cannot be created or destroyed, only transferred or converted. The second law of thermodynamics states that the total entropy of an isolated system can never decrease over time, and that natural processes tend to move towards a state of higher entropy.
