I discovered Thermodynamics principle is a half-truth. There are some proofs that the Law of Conservation of Energy is not always conserved and destroyed and not always constant. -
Computation proves that the principle of Thermodynamics is not always conserved and destroyed and constant. -
The applications of the explosion in the system of the principle of Thermodynamics. -
Wikipedia meaning of explosion: An explosion is a rapid increase in volume and release of energy in an extreme manner. -
Illustration 1-
I. The mixture of compressed air and fuel on the piston of an engine is not enough to move the piston up and down. The explosions increase and created an energy of the cylinder causing the piston to move. -
The petrol of 10Joule is not enough to move the car, the explosion increases and created energy causing the car to move. -
Illustration 2 -
A 15 ball billiard pool to be strike by white mother ball. -
F = 30lbs (White Mother Ball); D = 3ft (Distance from the white mother ball to the first ball to strike); W = Work, F = force; D = Distance-
The mother ball to strike the 15 ball is the work input-
The first collision is explosion followed by an increase in force and travelled distance by individual ball followed again a series of collisions. -
The mother ball transferred the force to the group of 15ball. The momentum is conserved to the group of 15 while the explosion increases to 15 individual balls. -
SOLVE FOR WORK INPUT -
W = F X D; W = 30lbs x 3ft = 90Ft. lbs -
SOLVE FOR WORK OUTPUT -
W = F X D; W = 30lbs x 3ft = 90ft. lbs X 15ball = 1, 350 ft-lbs. -
It shows the Energy increase by 15times. The elastic momentum was conserved from one piece mother ball to the group of 15. However, the explosion after the collision increases the momentum into 15. -
Illustration 3 -
For more heat energy the ball to replace with steel ball and steel sideboard. After strike is explosions of 15 balls. The explosion increases the group energy into individual 15. The work output higher than work input followed by a series of collisions that produces more heat more work output, more sound energy more work output, more travelling distance more work output. -
Illustration 4-
To get even more energy output without increasing the work input. Put an additional two groups of 6balls in a triangular shape to be placed somewhere at the back of 15balls at least 4inches apart from the sidewall and back wall. A total of 15balls + 6balls + 6balls = 21balls. The explosion creates collisions after collisions increasing the energy output. -
After explosion the work done increased 21 times. That principle can use to make free energy machine. -
The Law of Momentum states that the total momentum of two or more objects acting upon each other does not change, without external unbalance forces. -
In this situation after the first collision is an explosion that increases the momentum from one body to multiple bodies-
Thank you. -

Other question- in the isobaric process example, it seems like the gas cooled when the piston was pushed down. I understand that in the equation, a temperature decrease would balance a decrease in the volume of the container. But, by what mechanism does this happen? I can't figure out -how- decreasing the volume would cause the gas to cool. It seems to me like if anything, doing that would actually cause the molecules to move even faster, although to an imperceptible amount. And after all, as she said, we're doing work on the system, so unless there's an exit for heat, wouldn't the internal energy increase? Would pushing the piston down not just raise the pressure of the gas in an inverse ratio to keep the left-hand side of the equation of equal value?

Hey quick question for those interested. How much do you need to cool a solar cell operating at, let's say, 23% efficiency?
My thoughts are that a solar cell should not change its internal energt U, so in other words deltaU or dU/dt should be 0. So 23% of the solar energy becomes electrical work, while the rest of the sun's power (1-0. 23=0. 77) becomes heat that accumulates in the solar cell.
In order for dU/dt (delta U) of the solar cell to be 0 you need to fulfill Q=W, so in other words you need to cool the cell to such an extent that the only heat that isn't cooled off equals the electrical power of the solar cell, in this case 0. 54 times the power of the sun?
Is this way of thinking correct? I would very much appreciate any input.

Wait- around 2: 15 she says that the First Law only describes Heat and Work, because if a system is closed, then those are the only two things, and they're equal to each other. Therefore, she says, the First Law is just restating the Conservation of Energy. But in that case, wouldn't deltaU just be 0, making the term unnecessary?
I understand the Law, but I'm not sure she explained that correctly. Or am I misunderstanding?

The universe expands, also the universe before, we are come from out of a whitehole/blackhole is expanding. New expanding space means new place for energy and after the opened event horizon we are probably a tinier molecular universe inside a gigantic quark or something, what's mean more place for more energy.

So what they mean by entropy being disorder, they mean that when something-s molecules are like, -bouncing all over the place-, like they are in a gaseous state, there is higher entropy because the molecules are in more disorder than they would be in a solid state, and more heat is being released.

Informative and engaging, but she talks too damn fast. I have to pause and/or rewatch the video several times to actually understand. I understand they probably want to keep the videos short of less than 10 minutes, but just split it into two videos next time please.

this thermo video is already annoying. the work done by the system is + here. some thermodynamics books use this way. lets be inconsistent, you the one putting heat in, that is +. you the one pressing the piston that should also be noted as + to be consistent

if u think she speaks fast just go to the setting button in the bottom( where u can enlarge the screen, click it and click playback speed and choose slower speed so the video will become slower.
