That bottom one lacks an equal sign...

"The numbers Mason! What do they mean!?"

8 years ago | Likes 1 Dislikes 0

That last one doesn't have an equals sign, so it's not at all clear what it's supposed to mean.

8 years ago | Likes 1 Dislikes 0

I love the way i don't even understand the first one :p

8 years ago | Likes 1 Dislikes 0

Wait, there's no equal sign on the last one. Is this a mathses that I don't knowses?

I think I remember the second one, deep in the depths of my memory, and I'm glad that's how far in the list I can go.

ideally you've studied the chapter before class so you're not bouncing your head off der waals.

I am currently studying for my thermodynamics-exam... this shit it too real!

As a graduated chemical engineering major, this gives me Vietnam flashbacks

Politicians: "P times V equals nRT. The commies will try and say it's more complicated than that. Don't you believe their propaganda!

8 years ago | Likes 1 Dislikes 0

Product of pressure and volume equals product mols of gas times temperature times the gas constant R. High school chem, no idea about rest

8 years ago | Likes 1 Dislikes 0

It's for ideal gases so I'm gonna guess the others are for real gases somehow

8 years ago | Likes 1 Dislikes 0

ideal gas law, i learned the first bit

8 years ago | Likes 1 Dislikes 0

Bio major guy here. Explain the joke

8 years ago | Likes 1 Dislikes 0

You maybe have used the ideal gas equation once or twice? But the less idealized the conditions get, the more shit pops up in the equation.

8 years ago | Likes 1 Dislikes 0

Its the expansion of the ideal gas law into various subparts. seems simple and gets progressively more torturous to solve.

8 years ago | Likes 2 Dislikes 0

Ironic how the ideal gas equation expands to occupy all the available volume.

It's a nerd joke. I could do the same for all of my aerospace stuff. Especially solving the math for an autopilot as a 9x9 matrix equation.

8 years ago | Likes 2 Dislikes 0

This doesn't even include differential equations

8 years ago | Likes 1 Dislikes 0

It does not, but every one of those variables could represent a Diff Eq. not terrible to solve though, just use matrix math

8 years ago | Likes 1 Dislikes 0

Partial differential equations. Eww!

What's n=?

8 years ago | Likes 1 Dislikes 0

And v (lowercase) is the volume per mole, v=V/n, so the first formula can be rewritten as Pv=RT

8 years ago | Likes 1 Dislikes 0

Engineers like to use the mass of gas, and use a different gas constant for each gas. Dumb? Yes. But is it helpful? Unfortunately not.

8 years ago | Likes 1 Dislikes 0

N is the amount of substance of gas (in moles)

8 years ago | Likes 2 Dislikes 0

number of molecules, typically in moles.

8 years ago | Likes 1 Dislikes 0

or atoms, in case of monatomic gases

If that we could all live in an ideal world. Alas! 'Tis not to be.

When I have gas, it tends to be unideal.

It's only as if math is pretty bad at some parts of explaining the universe ..

Mathematics are the worst form of explanations, except for all the others.

In my field I usually just hand wave reality away and use the ideal gas law anyway.

Aerodynamics

You'll learn the second equation in chem II and the rest sometime before you graduate

8 years ago | Likes 8 Dislikes 0

It's just better approximations of a physical law, they're really not that big of a deal if you're an undergraduate.

8 years ago | Likes 4 Dislikes 0

The first equation is the ideal gas law. The rest are derivations towards the reality. Like in physics you have frictionless vacuums

8 years ago | Likes 3 Dislikes 0

Then you get into upper level classes, and they're like, oh yeah, friction's a bitch and so is aerodynamics.

Engineers have it too. Ideal gas law.

I thought the ideal gas law was enough to keep the tubes primed but not so much you shit yourself

These my friend, are the malevolent beast that crawl out of physical and quantum chemistry.

Often the more math you major has the more the jobs pay afterward. The more the job pays the quicker you can retire early.

8 years ago | Likes 1 Dislikes 0

I speak chemistry. Eq1 says: "If you fill a balloon with gas and cool it, it shrinks. Pressure x volume is proportional to temperature."

8 years ago | Likes 11 Dislikes 0

Eq5 says: "Let's mix 10 million different gasses together and do a bunch of stupid shit to it, and then not define any of the variables."

8 years ago | Likes 14 Dislikes 0

"What would be extra cool is if I wasn't even a real equation. Seriously, can you find an = or a proportional sign in me anywhere?"

8 years ago | Likes 13 Dislikes 0

What exactly is this equation

8 years ago | Likes 14 Dislikes 0

First one: pressure times volume of an ideal gas is proportional to number of particles times temperature.

8 years ago | Likes 6 Dislikes 0

It's the pervert equation.

8 years ago | Likes 1 Dislikes 0

Correlates pressure and temperature of a fluid with its volume/density. The colder/more pressurized, the denser. First one's OKish for gases

8 years ago | Likes 1 Dislikes 0

It's called Virial Expansion. Every picture are higher order corrections. It's used for gases and liquids with low density

8 years ago | Likes 5 Dislikes 0

The first equation is the Ideal gas law. Clapeyron stated it at 1834.

8 years ago | Likes 4 Dislikes 0

And the rest is the addition of all the variables to allow for non-ideal parts of it.

8 years ago | Likes 4 Dislikes 0

First one is for ideal gases then the next ones are for everything not ideal needing more information/variables to solve.

8 years ago | Likes 28 Dislikes 0

I understood some of those words

It tells the pressure a gas exerts on a container given certain conditions. The first one is "close enough," but wrong. The rest get closer.

8 years ago | Likes 5 Dislikes 0

It's like Newtonian gravity. It's wrong, but easy, and depending on what you're doing, good enough.

8 years ago | Likes 5 Dislikes 0

Isn't newtonian gravity correct when used on objects of smaller mass? And Einstein's theory can be used universally
