MCAT and Charles/Boyle/Avogadro's Laws

[pritomd]

Hi all

I am going through my ExamKrackers books, and I just came across something that said that we don't need to memorize the names for Avogadro's/Boyle's/Charles' laws as per the picture below.

The thing is, I recall from either my Kaplan (class) diagnostic or science assessment exam that a question was asked explicitly asking which of the presented formulas was Boyle's law.

I'm guessing this may have been on the science assessment now that I think about it since it wasn't a passage based question and it seems like a "background" type question..I'm realizing that now as I type this..but anyways,

Has anyone come across needing to match Charles/Boyles/Avogadro to their respective equations or anything related at all in an AAMC practice test or anything related?? Such as "use Avogadro's equation to ....."

Thanks in advance.

boyle doesn't boil (means no temperature), PV = PV

charles = tv (meaning only temp and volume) V/T = V/T

boom. there you go, time to move on.

Haha yeah, it wasn't that big of a deal since it's trivial to memorize which names match up with which relationships, but I was just curious since if there WERE something on MCAT's that require you to know the names, then EK would be writing something wrong.

Bahaha this is one of the few mnemonics I'm going to bother learning, if only for the comedic value.

I dont agree with a lot of what EK Gen chem says about MCAT... honestly looking at Berkeley's for comparison, I dont think EK does enough of a mathematical review or deep enough content review to really 'get' general chemistry. It has the same problem for physics, but there i dont think its as pronounced even though it is still pretty bad when you compare to BR.

Big boy Boyle sat on a kid and flattened him. Increased pressure = decreased volume.

Fat Chuck was popping some corn while watching the movie. Increased temp = increased volume.

Avogadro is the weirdo that liked counting molecules. Increased moles = increased volume.

TBR is amazing.

You Boyle potatoes and veggies (PV)
Charlie Brown is on TV
and Guy's cause teen pregnancies (TP)

That's how we learned them 😀 and all you really need to know is that Boyle is the one that is the inverse relationship. Know the laws and what they mean, but I don't think the names are important...

wow.

Like others have said, I don't believe the names of each of the laws are as important as just knowing the laws. With that being said, I'm pretty sure the names of each of the laws still falls underneath the category of what could be on the mcat, it's just not very likely.

TBR ftw.

I dropped a can of coke on my foot while filling the fridge up (trying to carry several at a time, not a good idea). After swearing profusely, I instantly thought about Henry's law, why it would have been best to hold it closer to the center of mass, and frictional forces. Ah MCAT... what have you done to me?
