Have you found the difference between x' and xi yet?
Get Tusselad to help you, he's a troll like you.

Nice one:

From your own link:
| HOW DRY ICE IS MADE
|
| The first step in making dry ice is to compress carbon
| dioxide gas until it liquefies, at the same time removing
| the excess heat. The C02 gas will liquefy at a pressure of
| approximately 870 pounds per square inch at room
| temperature. Next, the pressure is reduced over the liquid
| carbon dioxide by sending it through an expansion valve into
| an empty chamber. The liquid will flash, with some turning
| into gas causing the remainder to cool. As the temperature
| drops to -109.3°F, the temperature of frozen CO2, some of it
| will freeze into snow. This dry ice snow is then compressed
| together under a large press to form blocks or extruded into
| various sized pellets. Dry Ice is much heavier than
| traditional ice, weighing about double.

By the way, found the difference between a physicist and a
physician yet?

Why The Physics Establishment Is A Historical Laughing Stock

An examination of this video

http://video.google.com/videoplay?docid=-7750532340306101329

reveals that the collapse of WTC 7 started at second 17 and completed
at second 23. That is a total of 6 seconds.

It can be easily shown that this building collapsed in the same time it
would take an apple to fall from the roof of this building and hit the
ground - a freefall.

Let's do a simple calculation:

distance travelled = initial velocity * total time + 1/2 *
acceleration * total time^2

or

s = ut + 1/2at^2

Since the apple was stationary before falling (just like building was
prior to collapse), u = 0.

Since the height of the building was 174 meters, s = 174.

Since we are at ground level the gravitational field strength is a
constant, so a = 9.8 m/s^2

Now,
174 = 0 t + 1/2 9.8 t^2

Solving for t
t = sqrt( 2 * 174 / 9.8)
= 5.9590

Well look at that, an apple would take 6 seconds to fall from the roof
of WTC 7, just the same amount of time it took WTC 7 to collapse.

The 10 year old intellect can easily deduce then that WTC 7 must've
freefallen, further deducing that the ENTIRE STRUCTURE MUST'VE
COLLAPSED SIMULTANEOUSLY.

No minor fires can do that, _ONLY_ synchronized explosions can.

That, ladies and gentleman, evidently exceeds the boundaries of the
competence of our 'leading physicists' - the Wittens of the world, the
Wheelers, their loyal groupies, those so called 'experts' who love to
sell fables on gravitation and call others 'laymen', those who love to
tell others that they 'have no chance'.
