EDIT: Thanks for all the great answers. I've never really paid attention to the "Nitro" drinks before. I though Nitro was just a marketing tagline for ENERGY.

Now i'm going to start a Kickstarter for my new cabbage flavored energy drink with methane gas!

Why is 90% sulfuric acid more corrosive than 99% sulfuric acid?

Posted: 04 Sep 2016 12:18 AM PDT

I tried doing some research on this but the only reason I can find that explains this is that 90% acid has a higher water content. However, that is not too clear to me why the extra water content affects corrosion.

Can someone please explain the criticisms of the Myers/Briggs personality test?

Posted: 03 Sep 2016 09:37 PM PDT

I was recently asked to take the test. I was given the INTJ type and when I read the description I felt it was accurate, however I couldn't shake the feeling that this is just a modern day horoscope. So is this test widely accepted? What are the valid criticisms against it?

Edit: Thanks for the answers, folks. You were able to put some of my feelings into words much better than I could.

Do things cool off in space?

Posted: 03 Sep 2016 08:02 AM PDT

I'm sure this is a stupid question but if there is no matter in the void of space to get the heat transferred to, wouldn't a hot thing sent to space just remain hot?

How fast would one need to accelerate a container of air to make it bunch up to one side, creating a vacuum on the other?

Posted: 04 Sep 2016 04:59 AM PDT

Back when railroads were new, alarmists feared that the speed of the carriages going as fast as 20mph would create a deathly situation for the passengers. This was obviously quite wrong. But how quick of an acceleration WOULD be needed to start heaving the air in a contained space over to one side of it?

What does the wave function Ψ look like for an hydrogen atom?

Posted: 03 Sep 2016 08:45 AM PDT

My understanding is that you obtain the wave function for a system by solving the Schrodinger's equation for that system (I apologize if I'm actually basing my question on a wrong premise). So, assuming the system is a simple hydrogen atom in it's ground state, what would the wave function look like? And for a hydrogen molecule in the ground state?

I'm asking this because even though I was reading about this stuff, I never actually saw the wave function itself.

Thanks!

How does scientist determine from this one little white speck that it is orbiting Jupiter? How does speck in image become verified discovery? How does the scientist even know he has discovered something new?

I have read that having lots of neurotransmitters adds complexity to the signal but I dont understand how. Because the action potential is either fired or not fired. If possible could you provide an example that shows why 2 neurotransmitters would not work.

Posted: 02 Sep 2016 03:40 PM PDT

It is my understanding that a man has a 50/50 chance of having a son or a daughter depending on if the sperm that reaches his partners egg is "male or female" (carrying the X chromosome or the Y chromosome). If a man has an abnormal XYY sex chromosome are his sperm cells more likely to carry the Y chromosome as well?

What would happen if you passed High Voltage through water under pressure high enough to prevent the formation of gaseous water?

Posted: 02 Sep 2016 07:45 PM PDT

And by high voltage, I mean beyond the dieletric breakdown threshold for water.

At sufficient voltage, current, and heat, the electrons are stripped away from their respective molecules/atoms, forming a plasma, but I'm curious as to what would happen if the system were at a pressure high enough to prevent the formation of gaseous states?

Why is viscosity sometimes expressed in "Pa" and sometimes in "Pa*s", and how to convert?

Posted: 02 Sep 2016 09:02 PM PDT

Hello,

I am doing a literature review on viscosity of a certain material (in biology).

Most of the papers I have found report the values in Pa*s which is fine since I can understand it and convert it to cP.

However, some papers report viscosity in "Pa". How could I make it comparable to the rest of the papers?

What does the female hormone cycle look like before menstruation (I mean before menstruation starts altogether, not before it starts within a monthly cycle)?

Posted: 02 Sep 2016 03:17 PM PDT

I've google searched for graphs/articles to no avail. All the charts show the cycle after menstraution begins, or of levels from age from birth to death, which is too zoomed out to see what a level cycle looks like before menstruation :/

If it helps for why I'd like to know, I'm interested in how the female cycle functions before menstraution compared to after, because I'm considering cycling my hormones, as I am transgender, and doctors have normally only prescribed flat rate doses, which does absolutely nothing to mirror the genetic female hormone cycle and perhaps is a contributing or even primary factor for why transgender women achieve less feminization in comparison to genetic women (i realize age is probably the primary factor, but i can't rule this out--in fact i could have a chance at more hip growth because I am 22, and pubic symphisis usually closes around age 18-20s and ive always been a late bloomer with male puberty so I am obviously being hopeful with this).

I have seen it noted elsewhere that the expansion of space is not measured as distance/time (i.e., velocity), but simply as 1/time. Is this correct, and, if so, what does that mean? Does this just mean that space expands by a certain percentage per unit time?

Also, is there a theoretical limit to the rate of expansion?

Are there non-negligible losses to the earth's ecosystem when harvesting energy from natural processes?

Posted: 01 Sep 2016 11:33 PM PDT

Earlier I asked this question in response to a Futurology post about Iowa's recent commitment to 100% renewable energy, and thought I'd re-phrase it for /r/askscience since there seemed to be some interest:

[notice: this is a speculative question only] Given the processes of "harvesting" energy from "renewable" sources (such as wind, hydro-electric, solar, geo-thermal, tidal, etc) involves collecting mechanical or chemical potential energy their respective systems, do the amounts of potential energy we currently or could possibly harvest from them have a negligible impact on their respective systems? In other words; does the mass harvesting of wind energy effect global weather patterns? does it effect local weather patterns? Does it slow the travel of ground level air enough to have a measurable impact? Does the collection of tidal energy slow the slop of the ocean enough to effect tides? Does the collection of solar on a large scale actually cool the planet by collecting and reflecting solar energy before it has an opportunity to heat up the environment?

I apologize ahead of time if the questions I ask have already been answered and disputed, or are completely irrelevant given the available energy options we have. I am not an environmental science and dont understand the numbers, however I do know enough physics to understand that the energy must come from somewhere (mechanical, chemical) and means a net loss from the harvested system, never-mind the losses in transferring energy from one state to another.

How does a polymer such as nylon behave when placed in boiling water?

Posted: 02 Sep 2016 03:23 AM PDT

When it comes to alkalines, it's generally known that most of them have very low heat resistance, with melting points around 200 degrees C. Water boils at around 100 degrees C, so in theory there should be no structural damage to a piece of nylon fiber, right? That is, there wont be an excessive amount of nylon strands left in the water after the nylon piece is removed.

I am asking this because my mother is very sceptical to the usage of plastic in direct contact with food / drink, especially when there is heating involved. A good example would be tea stored in teabags made out of nylon-like material instead of paper.

Also as a bonus question: What kind of effects would the consumption of plastic have on the human body? (Short and long-term)

Posted: 01 Sep 2016 04:17 PM PDT

Given heatwaves, just as light, are e/m-radiation (infra-red) it's surprising humans cannot see them.

It's a great perk both for the prey and for the hunters. You can see the lion hiding in the bush and can sense which of the holes in the ground are inhabited and which are not. And yet human hunters (including army and police) have to rely on special cameras to extend their visible spectrum.

Has their sight been nerfed along with their smell, fur and fangs because they were too op or is it a hardcoded cap in the spectrum, i.e. not a thing with any other animal as well?
