Stevmg, I can not see how the velocity of particles could be the same high up as they are down low within this closed system. Like a ball or bullet, a gas particle is affected by gravity. When a gas particle moves by its own velocity from a lower position to a higher position within the...

Now I would absolutely agree that, if two bodies of gas come into contact with each other (one on top of the other) and at their point of contact, that a 1C temperature gradient existed, that heat would transfer from the hotter to the colder. But when it it comes to the example I there is...

Does anyone agree with the above statement?

every particle that moves up loses heat energy to gravity; as the mean velocity of a particular level has been determined by its fall, the average velocity of particles entering a particular level are going to be the same as the particles in that level. em radiation would allow heat energy...

The thing is, the line of best fit has to go through the mean of the population. I think you will find their are instances where multiple lines can exist, but for the most part they don't.

Now to help me understand this, i will need a time based description of how this occurs in a particular instance. Imagine a planet covered in an atmosphere of ideal gas. On this planet we have our super-long insulated upright tube, but at this moment, its a vacuum; nothing is inside of it...

What are these thermal agitations?

I've clearly jumped the gun on this one, the formulation doesn't match up with the minimum sum of absolute errors. The best example of this would be to compare the data set [(-10,0)(-1,-1)(1,1)(10,0)] and [(-20,0)(-1,-1)(1,1)(20,0)] they both have the same line of best fit, but you would...

I've had a bit of a rethink about this and I'm not getting something. T= (mv^2)/k Naturally a particle will be affected by gravity, so as its velocity moves against gravity, it will slow and if ones velocity has it moving with gravity it will speed up. T= (mv^2)/k so changes in velocity...

The issue has to do with determining the gradient between an individual that has the same values for x and y as the mean and the mean, It's anything and everything as they are in the same position. As a result I've had to change the definitions of y, x and n, so that they are not inclusive of...

Say if I state that the definition of the line of best fit, is the line which achieves the least absolute errors, when measurements from the line are taken perpendicular to the line. (The measurement is at right angles to the line) Is there some way of determining if this is a more robust...

I've been told that their exists no perfect mathematical method of obtaining a line of best fit from a population of data. This doesn't make a whole lot of sense to me, so I have made an attempt at doing such (see google docs link)...

Say if two synchronised clocks are at either end of a spacecraft . when the spacecraft accelerates, the clocks accelerate at different speeds due to length contraction and so are not synchronised post acceleration, according to a non accelerating observer who considered the clocks...

I really have difficulty seeing how a heat gradient can be compatible with the Clausius statement. You could add heat energy at the cooler top and watch the heat energy passively spread to the hotter bottom. Unless someone can explain why that wouldn't happen or how I am misinterpreting the...

so what gets your backing? (1) a temperature gradient will not appear in a body of gas. (2) a temperature gradient will appear in a body of gas, but the same kind of gradient will appear in anybody of gas. (3) a differing temperature gradient will appear in different bodies of gas of...
