How do hot air balloons work?

One of the most surprising things about air that may not be intuitive is that it is a fluid and like any other fluids exerts a pressure on objects.

Standing on earth with layers of air above us, we are constantly being ‘weighed down’ by a pressure of  ~1atm at all times.

All objects in air are also assisted by a buoyant force that is caused from the pressure  difference between the top and bottom surfaces.

Let’s now consider the hot-air balloon in particular. A force diagram is probably the best way to start:

Therefore we see that in order for the hot air balloon to float, we need to have the buoyant force compensate for the net weight from the balloon, the load on it and the air inside it:

And with a spectacular burner onboard our hot air balloon, we can easily increase the temperature of the air inside the balloon!

That’s pretty much how hot-air balloons work! You increase the temperature of the air inside the balloon to go up, decrease the temperature to go down and skillfully adjust the temperature to hover.

Have a great day!

Questions to ponder:

When you increase the temperature of air, its density decreases. What do you think happens to all the molecules that were previously inside ? Do they exit the balloon ?

Different shaped hot-air balloons is a common sight. Do you think that the Buoyant force changes for each shape?

How do you think Helium balloons work ?

huh that seemingly unpleasant task only ended up taking eight minutes to complete and was surprisingly satisfying, I may have erred in putting it off for two weeks.

If courage isn’t the absence of fear but doing the right thing regardless of it, maybe confidence isn’t the absence of insecurity but knowing you have real worth despite it

[oncemylove-deactivated20180625]

this is beautiful

[randomslasher]

By this same token, maybe goodness isn’t the absence of bad thoughts or impulses, but the conscious choice to behave according to your moral ideals in spite of them.

really love imagining a bunch a kids and teens on their pokemon journeys staying the night on the couches and floors in the lobbies of pokemon centers, having long talks about their experiences and feelings sharing funny and scary stories and myths about legendaries and trading items and sharing TMs along with sugary snacks and pokedex chargers all while their pokemon are out of their pokeballs and all bundled up in blankets sleeping soundly next to their trainers while they stare up at the stars shining through the glass ceiling over their heads

dude seeing these Mega high quality images of the surface of mars that we now have has me fucked up. Like. Mars is a place. mars is a real actual place where one could hypothetically stand. It is a physical place in the universe. ITS JUST OUT THERE LOOKING LIKE UH IDK A REGULAR OLD DESERT WITH LOTS OF ROCKS BUT ITS A WHOLE OTHER PLANET? 

[i-homeostasis]

LIKE THIS JUST LOOKS LIKE IT COULD BE A PERSON’S BACKYARD. LIKE YEA A LITTLE DUSTY MAYBE THERE WAS A SANDSTORM BUT THAT’S COOL I’M JUST GONNA WALK DOWN TO THE STORE P S Y C H YOU’RE ON MARS BICH!

So I used to have a Russian friend who had a pretty thick accent and like a lot of Russians tended to eschew articles. She would say things like “Get in car.” And stuff.

Well one day this asshole who had been kind of tagging along with us asks her why she talks like that because it makes her sound dumb and I still remember her response word for word.

“Me? Dumb? Maybe in America you have to say get in THE car because you are so stupid that people might just get in random car, but in Russia we don’t need to say that. We just fucking know because we are not stupid.”

[annarcho-nicolesmith]

One time I was proof reading a paper for a Russian student. As I was correcting her paper with her, the many mistakes in her grammar started weighing on her. I asked her what was wrong, and she said, almost sobbing,

“In Russian I am so intelligent and clear. In English I am like [an] idiot”

Respect to anyone trying to master a foreign language. I get so sad thinking about that student.

Full offense but people who make fun of someone else’s accent or belittle their limited vocabulary when they’re speaking a language not native to them are fucking disgusting and are just begging to be punched.

They’re speaking your language because you don’t know theirs. That’s not something they should be made fun of, it’s something that should be commended because learning a language is hard fucking work.

I hate people who do this so much.
