Where'd S/N Go?

First you go to the bottom where it says display options. It'll look something like this.



Then bring down the drop down menu and go down to 1 year.



Then click show threads.

Third pic for my post.

Hope this all helped.

talk about details...


could you explain the principles of thermodynamics one more time?

First law of Thermodynamics : the sum total of the energy in a system and its surroundings, over time, is constant (Conservation Law).

If we consider an atomism as a system that is difficult to break apart (an experimental observation: equally applicable to social groups and social bonds), there is energy in the bonding of atomic constitutions that has to come out of the environment, and when that bonding is broken that energy is released.

Dfn. Forms of energy, e.g.: Heat (q)=exchange of thermal energy (stored as kinetic energy of atomisms, i.e., movement, where the "heated" or diffusive movements of atomisms are uncorrelated, net undirected)=the capacity to diffuse kinetic movement via collisions from "hot" bodies to "cold" bodies in a unit of time; Work(w)=net directed (convective) movement of matter from one location to another = external force x distance moved.

Note that work requires an external force (and thus energy from the surrounding environment). Heat, on the other hand, tends to equipartition thermal energy via diffusive collision and thus tends to thermal equilibrium: within a system at equilibrium there are no further gradients to do useful work (see second law).

Dfn. Thermodynamic engine: A (nonisolated) system where energy is transferred from the surroundings to do work. E.g., when a piston is moved by heating gas in a chamber, the work done is PV (pressure x volume).

The energy in a thermodynamic engine is sometimes described by its enthalpy H= E +PV where -PV is the work done and +PV is the correction for energy used in doing work on the surroundings. H is the capacity of energy differentials to diffuse heat (relative to a surrounding) or to do work.(Because thermodynamic engine processes are often cyclical, and depend on discrete quanta of energy per cycle, H may be quantized).

Energy and enthalpy are state variables of a system. If heat and work are the only forms of energy transferred between a system and its surroundings in a closed system, then the first law states for enthalpy: E2-E1 = Dheat + Dwork = q + w, where D is the symbol for change in a quantity.

Chemistry involves the study of bond energies (enthalpies) that are released when a bond is are broken and consumed when a bond is made (changes of state). For chemical transformations at a constant (e.g., atmospheric) pressure, the change in enthalpy will be q; typically, some quantum of energy


I'll get onto subsequent laws later. Right now, my fingers are tired.

i'm sorry i'm not sure i understand... could you rephrase that please?

If you didn't understand it, why'd you ask?

i think i can answer ur question the way 97v6silver might....

Cliff Notes

1ne at0m = teh b00m
uder at0m = teh baM
teh b00m = teh baM
antser = teh s0lv'd

meh = teh w1n!

no i understand fine, i just wanna keep you working...

nothing is EVER easy on the V6 boards, its always a production! teh wo0txz0rz
