On the right side, k_B Is called the Boltzman constant, and omega (Ω) is the number of possible “microstats”. Let me explain with an example: let’s say that I have four pieces and four people. How many different ways can I share these pieces? Well, two extreme cases would be that everyone gets a room or the four rooms go to one person. In total, there are 35 possible distributions. These are the microstats (Ω). You can therefore consider them as possible provisions of AMERG energy particles while keeping the total energy identical.

If I go to basketball, its potential gravitational energy decreases when it falls and its incases of kinetic energy – total energy is preserved. But it does not bounce as high as it started. Indeed, a certain energy escapes in the form of heat on the impact. The ball warms up in a little. When we take this thermal energy, we see that the energy is motionless. But entropy is higher.

But if the ball had Colder and boun Higher? This would mean that thermal energy is retained and the Incasses of kinetic energy. Energy Always Be kept, but in this result, entropy is traced. This is actually possible, but you have this experience until the end of time and never this result.

Here is another fun example. Imagine putting ice in a glass of lukewarm water. Is it possible that water warms up and the ice cools? Again, the probability is not zero, but it is extremely improbable. Boltzmann’s formula says that the more possible microstats, the greater the entropy.

UltimoteLly, this leads to the second law of thermodynamics, which stipulates that the total entropy of a closed system can only be embodied over time, or at least it can never decrease. I know, as, your office will only disorder and more disorderly, unless you open this “system” and do “work” – which, do not forget, means adding energy. Unfortunately, the universe is a truly isolated system, so it can only end in a way – in the total loss of any stutch and life.

4. Ohm law

This equation is used in many of our modern devices because it deals with electricity. Ohm’s law gives Bethaeen a change in potential electric energy (ΔV) through certain elements of a circuit and electric current (THE) Moving through this element. Because it is tiring to say “the change of electric potential”, we often call it “tension”, as it is measured in volts. Constant proportionality Bethaeen The voltage and the current are called resistance (R)); Unsurprisingly, it is deserved in Ohms units.
