Gases are everywhere, and this is good news and bad news for chemists. The good news: when they are behaving themselves, it's extremely easy to describe their behavior theoretically, experimentally, and mathematically. The bad news is they almost never behave themselves.
In this episode of Crash Course Chemistry, Hank tells how the work of some amazing thinkers combined to produce the Ideal Gas Law, how none of those people were Robert Boyle, and how the ideal gas equation allows you to find out pressure, volume, temperature, or number of moles. You'll also get a quick introduction to a few jargon-y phrases to help you sound like you know what you're talking about.

It's actually -273.15C

At 5:37 - decreasing the number of miles decreases the volume, but in the case of a balloon the pressure actually goes up because pressure is related to curvature (this is why it's hardest to blow up a balloon when you're starting it and then it gets easier).

@raefstewe.923 6 лет назад

In a series of experiments with his friend, Richard Towneley, Power discovered the relationship between the pressure and volume of a gas that later became known as Boyle's law. This relationship was outlined in "Experimental Philosophy." However, many may argue nevertheless that Boyle, after discussing the theory with Towneley and reading a pre-publication manuscript of "Experimental Philosophy" cited the hypothesis as the sole work of Richard Towneley. Boyle's mention of the theory preceded the publication of "Experimental Philosophy" by one year, which, combined with Boyle's promotion of the idea and his significant status as an aristocratic scientist, ensured the theory would be known as "Boyle's Law." [5]

@jtswanner 9 лет назад

I love Crash Course! Just wondering... think maybe you could make them less crashy coursey? You know, pause for breath between words now and again. I would love to see these episode lengths go up to the 22-23 minute mark so that we can allow students to have more internal processing while the video is still playing in class. ( for example, show more experiments, maps, illustrations, practical demonstrations, real world applications). It doesn't have to be Thoughtbubble (I know your contract and collaborations with them are limited and specific), but just maybe some other way of illustrating and expounding on whatever the lesson of the day is. Just a thought. Wonderful work you and your brother do! Huge fan, keep it up!

@PermanentMarkerism 8 лет назад

That would be so much work and this is free education. I think this fast method is kinda cool, quick information with colors and little animations that compare things like the cation animation to help you remember if you're particularly interested you simply do your own research.

I love that can experiment, that's just amazing. Especially since, from what I understood, since the atom in the can slowed down so much the air outside the can just busted through. The very air you're feeling broke though metal because inside the metal was too calm.

@LoveleshColaco 10 лет назад

Why don't you guys have physics crashcourse

@hyperx3495 9 лет назад

See, them doing a physics crashcourse is easier said then done. They would need to teach a bunch of advance math, which not many of the viewers actually have that mathematical background knowledge.

@vixenthefox9792 9 лет назад

@XPimKossibleX 9 лет назад

Vixen TheFox i would also love a mathematics crash course, not that i'm in college but i find it incredibly interesting. the thing is that math is so incredibly broad i don't know how they would manage to do a "mathematics" crash course.
