On the right side, kB It is called the Boltzman and Omega constant (Oh) is the number of possible “microstates”. Let me explain example: say I have four coins and four people. How many different ways can I share these coins? Well, two extreme cases would be that everyone gets one coin or that all four coins go to one person. All in all, there are 35 possible distributions. These are microstats (Oh). So, you can think of them possible energy arrangements among particles, and at the same time keeping the overall energy.
If I throw basketball, her gravity potential energy decreases as falling and its kinetic energy increases the overall energy. But it doesn’t bounce as it started. This is because some energy leaks like warmth on a blow. The ball is warming up a bit. When we enter this thermal energy, we believe that energy is still preserved. But the entropy is greater.
But what if the ball has colder and bounced senior? This would mean that heat energy is reduced, and the kinetic energy is increasing. Energy would still Be preserved, but in this outcome entropy decreases. This is actually possible, but you can lead this experiment by the end of time and never get that outcome.
Here is another fun example. Imagine putting ice in a glass of water of water. Is it possible that the water becomes heated and ice becomes colder? Again, the probability is non-zero, but it is extremely unlikely. The Boltzmanna formula says more microstates are possible, the higher entropy.
Striving, this leads to the second law of thermodynamics, which says that the total entropy of the closed system can only increase, or at least it cannot be reduced. So, your table will only get a messier and messier, unless you open that “system” and do some “job” -Who, remember to add energy. Unfortunately, the universe is a really isolated system, so it can only end up one time – in the overall loss of all structures and life.
4. Ohm’s law
Kindness Rhett Allen
This equation is used in many of our modern devices because it deals with electricity. The Law on OHM gives the relationship between the change of electric potential energy (ΔV) over some elements in a circle and electric power (And) Movement through that element. Since it is hard to say “change of electric potential,” we often simply call it “voltage”, as measured in Volts. The proportionality of the constant between voltage and electricity is called resistance (R); It is not surprising, measured in the OHMA units.
