Girls vs Girls - Page 344

Aww, I was forced to miss everyone.  At one am our time, we finally lit off the final night work.  After a flawless evening, the very last big firework thing (a multi deal) sent off 2 of 15 rounds, before knocking itself over and flipping about with the next 13 shots.  Big balls of fire hitting the old barn, the wood fence, started 3 different grass fires.....   Just glad we talked with the girls about what their jobs in a fire were.  Little one turned on the hose (which we had next to the launch pad) and she and I started on the wood fires while Dad and Ruth ran and started on the grass fires.  We were barely able to get all fires out before someone called the fire department. 

Went out this morning to survey the damage, nice burned patches (its been soooo dry here) in the native grass area, behind the garage, at the base of many areas of fence and barn.  Didn't catch the barn on fire, or the wood fences, but only becasue we had the hose very close.  I'm telling you, 15 seecond longer would've had real inferno material.

How are you girls?  I totally meant to get on last night, but as is, I've got burns on 3 fingers from reaching into the barn from underneath the be sure the old wood wasn't on fire from the fireball wedging itself under it.  It was, but I got it out with my poor right hand and thumb and two forefingers.  It kinda hurts to type now, but the bandaids help the discomfort (of course, you don't want to know how many correctiois w/spell check their are going to be.)

BIg hugs, catch you later.

I nominated you a few months ago, but I'm not sure if they keep votes from past months.
Hey guys, good morning. Would any of you happen to know anything about entropy and isothermal compressions? Google is being unhelpful.

 Yes, a bit. 

In commen terms, enthropy is everything moving back where it wants to be.  Ice melts, sugar dissolves in water, when you run your car more and more enthropy develops from the inefficency of the motor, and creates wasted heat energy.  in this case enthropy is basically the unhappiness of the fuel being burned and foced to explode to move a motor, not all of the fuels energy is used for the motor, some makes heat (from friction - again things unhappy to not be in their natural state but forced to be part of a combustion reaction) 

You see, everything (even atoms moleculary) all want to go back to homeostatsis, or basically happiness for them.  Entrhopy always moves in one direction (ice melts, not forms in a cup on your table most times of the year) or stays still - water frozen because its in the antarcic or alaska.  SO, it either is going toward its norm (melted at 70* F) or is allready at its norm, and thus not moving.

Isothermic compression is more complicated, but you've got the enthropy part now.  As you know, isothermal comopression often involves gases.  In isothermic compression there are two rules:

If your working on a particular problem, come on after school, and I'll try to help you work through it, and understand the process.
