Oh c'mon Fier, we like having you and your not so making sense around

Hi K
And thanks. How are you?
Are you talking about the physics stuff? Oh yea, our physics assignments are usually a delight. This one has been especially long, for us to complete over the holidays

Kagu - hmm, black stuff on his waddles? Your not having nights cold enough for frost are you? My first choice is alwyas excess cold, it kills the skin, but Alaska ought to be not freezing in the summer at night, but if it is, its too drafty where he's sleeping.

otherwise, could be fungal infection. does it flake off? Is it stiffer and harder than surrounding flesh? does it smell? Got a pic?

Smell - Dunno

Stiff- yes

Flakes - yes

Pic - coming right up - really honestly it looks like dried blood but he hasnt been fighting!

Its been maybe around 45* at night but I dont think THATS it !

The specific question is How does the entropy of the gas change (if it does) during an isothermal compression?

The entropy of the gas shoud NOT CHANGE during an ISOTHERMAL compression. It will in other forms of compression yes, but isothermal means the temp (and thus the sign of heat from enthropy) will NOT change. Remember, heat is a product of entropy, always in evidence when there is entrhopy. In isothermal compression, there is no heat change. Thus, no increase in heat means no change of enthropy during (and only during) isothermal compression. Other forms of compression will show increased enthropy expressed by heat increase. (remember, gasses produce an incresing amount of heat in relation to the entropy they are suffering. enthropy is inatedly the inability of something to go against its nature, thus forcing it into phy/chem reascions.)

(wow, its been awhile since I studied this in college. I'm afraid if I say too much, I'll complicate things. By the time I was in Phy. II in college....well, lets just say if a little knowledge is a dangerous thing, I was a potential threat to mankind)

LOL! Well like when you had jokes i coulnt understand 'em !!


Oh and MARTY!!

Thanks Marty. That's very helpful.
(The other half of the question was about entropy of the surroundings, which increases)
And with that... phys assignment done. Muahaha!!

Thanks again!

How old is he? Are you chickens duffering from mites? (feathers dropping, looking scraggly between molts?) Wash his comb with warm water, maybe hold rag to him, and clean off genly what will come so we can get a look at whats going on here. Maybe he rubbed the top of it against something rough. They are chickens, and they do the darndest things. If you KNOW he's not fighting, and if its only 45* it can't possibly be frostbite, we must go with those ideas not allready subtracted.

BTW - so glad you read my PM and found out I am still your sweet friendly amiga.

I was a little hurt you thought I'd be mean just cause we tiffed, but I understand you were allready dealing with lots of heart owies, and feared I'd toss my own issues on you. Please never fear again. I'd never write a mean PM. I'd ignore you first, if you made me that mad.

Your welcome. I hope we got it right.

Its been awhile. Your always welcome to come ask me questions, I like to remember what I've learned.

How are you this evening? Still getting some guff from others who are judging you by age alone still? fools.

We all know all about that, right Kagu?

KAGU!!!

I'm sure it'll be okay. My phys teacher is a nice guy anyhow, he lets us give in our assignments for him to check first before he marks them officially.
Me too. I signed up for a junior school mentoring program, and I hang out with the year fives (fifth graders) during maths. They have a new girl from America who joined the class this term.

That seems to have subsided. At least the person behind it hasn't been online for a while... haha.
