Bois, can anyone explain this thermodynamics problem to me?
You change the temperature of an ideal gas, sealed in a container. In which of the following scenarios is the pressure rise the greatest?
A) Heating the gas at 150 ºC by 50 ºC
B) Heating the gas at 150 K by 50 K
My textbook says the answer is B), but I don't understand why. Please explain senpai

PV=nRT
P/T = nR/V = constant
So P and T are proportional
150K->150K+50K is an increase of 33%
150ºC (150+273K=423K) -> 200ºC (473K) is an increase of 12%
Pissing in someone's mouth is more effective than pissing in their pool even though you add the same amount.
In an isochoric (constant volume) system, initial pressure/initial temp= final pressure/final temp
Convert the Celsius to kelvin and plug the numbers in.
Oh shit, how did I not see that?
Thanks a lot famalam, you saved me xoxo
Daily reminder that if you are ignorant to the arts you will never make a good scientific mind.
on the contrary
you just need to be an asshole

Mathematics is an art so what's your fucking point?
>>8957908
Mathematicians like to say that, but it's really just a formal science.
Is analysis an important field if I am going to study physics? I find math interesting but I feel like some math concepts are useless in physics. What physics/math should I study doing the summer to be prepared in general?

By a methods book, I recommend Riley et al. You don't really need anything else, certainly not at an undergraduate level.

Theoretically, what is the most calorie-dense molecule that we could metabolize? Not necessarily asking for something that is naturally occurring. It could be theoretical, or hypothetical.
Are Jetson-style food pills a possibility?
>>8956546
You LOOOL
It would likely be a saturated fat
>>8956546
Protein and carbs are around 4 KCal/g
Fat is around 7 KCal/g
Just pure fat is about as dense as it gets.
Would Jupiter have continued migrating inward and became a hot Jupiter if Saturn never formed?

Can someone please explain what the Gravitational Constant actually entails?
Like what determines it? Space between atoms?
>>8956456
F=m1*m2/(r*r) is otherwise correct, but the answer is always 14983338527.6 times too big.
fix it with a constant G

If we were on the moon G would be a different value?
I am a nationalist but i do believe that if we want to advance as a people we should form some sort of international research organization. It could haul us decades forward, if not centuries. Does an organization like this allready exist?
>>8956386
Literally thousands
>I am a nationalist
Wew lad
Same boat as you OP. I'd be a globalist if I wasn't convinced everybody pushing is an evil power hungry monster.

Fuck that. Competition is a driving force in human development. Don't think for a second that putting everyone in one box would speed things up instead of slow us down. Just think about human cloning. We can't really get anywhere in human cloning technology because a few big world powers have decided that no one should do it, even though we have so much to gain.
Leaving technological developments up to a competitive free market is the best thing that can happen.
Thoughts on paying for Bootcamps, and how they compare to majoring in computer science
>>8956334
giant rip off. I learned how how to program in highschool. I'm a graduate student in applied math now and all the highschool level techniques still work.
just learn it yourself, paying out the nose for some "camp" won't make you any better than someone self taught
They are a meme.
>>8956334
>Bootcamps, and how they compare to majoring in computer science
They both suck. Learn the stuff on the wikia and make projects.

Is Mario Bunge the most /sci/ person currently alive?
Tell me which one works best for you:
1- Doing a metric shitton of easy-medium problems, and a few difficult ones.
2- Doing very few easy exercises and then delving into the difficult ones, knowing you will only be able to do a certain amount.
There's not a whole lot of difference between your two points?
I usually try to develope my own sort of introduction to a topic, rewriting it as I understand it better.
>>8956239
The difference is in amount vs. difficulty. "Many easy or few hard" would be an extreme synthesis.
