Arg. *Head banging against ... laptop* Why does this not make sense? I worked the silly air-pressure problem, like the good "hard-working" student I am, but when I checked it in the book it was like they were speaking Greek! I mean...*makes over-my-head hand motion* Completely...WOOSH! *Sigh* Ok...so...maybe you can understand Charles' principle better that I. Decipher this:

At 27 degrees C, an amount of gas has a volume of 2.0 L. What volume will it occupy if it is heated to 87 degrees C?
Ok, use the whole... V1/T1=V2/T2 when V1 is 2.0 L, T1 is 27 C + 273=300 K with a line over it. Now, don't ask me where on earth they got those extra numbers. I haven't a clue. Maybe they're like the French with letters and they throw a whole bunch of extras in there. Anyway... V2 is the unknown variable that we have to calculate and T2 is 87 C + 273 = 360 K with a line over it. Again, I HAVE NO IDEA where they get the #s from AND I have no idea what the line means. Oh. Wait it says here it means "the digit is significant"...Anybody? Anybody getting this? Ok, so you're suposed to substitute values into Charles' law and then cross multiply, cancel, cancel units, solve and then you somehow...I don't know how you get it...I don't know where they got it from, but SOMEHOW they arrive at 2.4 L=V2. See? See how easy that it? *Sarcasm*

I don't see why this is so complicated. E=mc squared made much more sense! I mean, who doesn't like Einstein's theory of relativity to convert matter into energy, right? And valence electrons! Who doesn't love valence electrons? I do! I looove them! We had some laughs. Back when things were easy and non-mathmatical. The periodic table of elements. *Wistful sigh* I looove that good ol' H2O, which, by the way, is a covalent bond {two non-metals}. OOH! And who doesn't love some good ol' Unununium {I kid you not; that's element #111, which means it has 111 protons in the nucleus}! Yep. Those were the days. *Dreaming of radioactive isotopes*

Ok, this post is boring enough as it is. Ciao!
