How do submarines adjust buoyancy? | [
"First understand that buoyancy is a factor of both weight and VOLUME. So while air under pressure has the same weight as air not under pressure, and volume of that air increases. So a sub has air and pumps that air into the ballast tanks where it is under less pressure. So now the same quantity (by weight) of air... | [
"Yes, the remaining helium still provides buoyancy, but there comes a tipping point where that buoyancy isn't enough any more to carry the weight of the balloon's casing."

How could someone possibly believe that the Holocaust did not happen? | [
"You need to look at it form the other direction. The atrocities the Nazis committed are used to invalidate many of the the positions they held. So if you support some of those ideals, in order to make them valid, you need to find ways to minimize their culpability in committing those atrocities."

Why do magnets with two poles become smaller magnets with two poles each when split up? | [
"Think of atoms in a magnet like a giant stack of lego bricks. Magnetism causes all of the atoms to line up the same direction so this stack represents a typical magnet. If you break that magnet in half, the orientation of the upper convex bumpy side and the lower concave side stay the same. It sticks back together... | [
"So any ferromagnetic material (a material that is attracted to magnets, and has the potential to be a magnet) is essentially composed of tiny, microscopic magnets. They're oriented randomly, so the magnetic fields cancel each other out, and it doesn't have a net magnetic field. To make it a magnet, you heat it up ... | eli5_question_answer | {

How does kinetic energy play a role in chemical reactions? | [
