Ok, yes. Put one mole of an inert gas into a constant volume container and measure the pressure at varying temps. If using the atm,mole,celsius,liter system you will find 22.4 liters at 0 celsius and 1atm no matter what. Then you can follow that line all the way to zero pressure and notice that...

In the back of my thermodynamics book it has large quantities of thermodynamics properties listed for water--ie temperature, pressure, specific volume, internal energy, enthalpy, and enthalpy. I would like to know how these tables are built and the methods used to ascertain the data in...

If I were to take a copper wire and shove it into the positive terminal of an electrical outlet and then stick the other side of the copper wire into the earth, will current flow??

I found some pertinent literature... http://www3.alcatel-lucent.com/bstj/vol04-1925/articles/bstj4-4-685.pdf

Can you elaborate on your first sentence? Everything else is helpful and made sense I think I may need to learn more about linear operations and how they affect their arguments

I am looking for a proof to why we can apply kirchhoffs laws and ohm's law in the s-domain. If anyone has an intuitive explanation or possibly knows of a link explaining it that would be awesome. Thanks

They state that the Earth ground cable connecting ground to the neutral wire inside the transformer is a feedback path for electrons. From that information I would conclude that without it the circuit would not be complete and current wouldn't flow. Then they follow by saying that the use...

Ok, I get it now. I didn't see the step of bringing that equation back into the PDE's. I was also confused on how the dp/dx was treated as constant wrt x but on the following page it shows that dp/dx is in fact constant and related to the viscosity and spatial properties. Thank you.

I am getting lost in the proof in the 5th line when it says there are 10 numbers that have the same kth digit as x. Why 10? I don't understand where this number is coming from and it doesn't seem arbitrary. the rest of the proof...

The definition of In is on the next link. In is a subset of R2 and is the line of equation y=n. I have to admit for some reason I was stuck on thinking this was an intersection. Thinking about it some more I have realized that the individual sets of the indexed union each contain a line. Those...

I am having trouble understanding how the indexed union of ln in the first picture is equal to a subset of the plane; an element of it is a point on one of the lines. If I were to choose say 0 1 2 then the indexed union should be y=0 union y=1 union y=2. These lines would have no points in...

What version are you using?

syms y int(2*y*(sqrt(1-(y-1)^2)),y,0,2) I plug this into MATLAB and I get the answer is negative pi. The entire integration region is positive. How is this possible! what the heck is going on? Just noticed that if I set the limits to 0.00001 and 1.99999 it works perfect. Can someone explain this

cylindrical pressure vessel with inner pressure P. Take a infinitesimal cube on the inner-wall of the vessel. When calculating the normal stress along the radial direction it is assumed that that it is equal to P on the both the negative \widehat{r} and positive \widehat{r} directions...
