The processes in thermodynamics that go by their own or form product naturally is known as a spontaneous process. In the spontaneous processes, the total energy of the reaction or process must be minimum and the entropy must be maximum.
Answer to: What is entropy? Although the total energy of the universe is constant, is the entropy of the universe constant? By signing up, you'll...
Is the entropy of the universe constant? View Solution Define the term density. Give its units and dimensions. View Solution What is noise ? What is its unit? View Solution Define the term pressure.Is it a scalar or a vector? Give its units and dimensions. ...
The geometry of the universe is determined by the density of matter within the universe. Albert Einstein'stheory of general relativitydescribes how matter can curve space, so the matter's density can control the curvature and geometry of space on the largest scales. The key value is the "crit...
“Heat is work, and work’s a curse, and all the heat in the universe, is gonna cool down. ‘Cause it can’t increase, then there’ll be no more work, and there’ll be perfect peace. That’s entropy, man.”
probability of a new particle being of some type “A” is proportional to the number of states that “A” can be in, which is exactly how you go about maximizing entropy. So, you can write off the selection of new particles as just another attempt by the universe to increase entropy. ...
Black holes seemed to reduce the entropy of the universe, because when the cup falls inside it is lost forever. Wheeler didn't like the whole thing. He turned the problem over to Jacob Bekenstein, one of his students at Princeton. To solve the dilemma, he proposed a generalized second ...

It is, however, been going through a gradual increase in entropy with time. The universe is like a computational machine, with its vastness unfolding and interacting with sets of universal rules. All that took place is just an instance of ongoing happenings across the infinite space. Everything...
As was explained in the preceding lesson, the distribution of thermal energy in a system is characterized by the number of quantized microstates that are accessible (i.e., among which energy can be shared); the more of these there are, the greater the entropy of the system. This is the ...
