@@cursed_xzy The main comment means the context about this video. Now be quiet, peasant. You've done nothing productive but scrolling in the internet, starting troubles.
We blew our chemistry teachers mind in college when he did this experiment, and someone asked, "But what if you pop the Ballon when the gas is cold compressed?". You could literally see the look of curiosity in the teachers eyes as he "popped" the cold compressed Ballon then watched it fully inflate as it warmed and then deflated....his reaction was just, "well, I didn't know that". The rest of the day was spent pondering the result as a class.
You guys are so lucky to have a school like that. I've always grown up in a school where we barely do the things in curriculum and fail to enjoy our class like that
@@techunboxingpro3295 lets suppose we are dealing with an ideal gas. The ideal gas equation is pv=nRT The gas go through a phase transition, therefore, the gas initially had a certain temperature, pressure, volume, etc. After the transition, some of these variables changed (it can be either the temperature, volume, pressure or all of them). We can conclude the the gas had an initial structure and after the phase transition, another structure, therefore: P1.v1=n.R.T1 (before the transition) P2.v2=n.R.T2 (after the transition) In this case we know that there is a change in temperature and a change in volume! We assume that the pressure remains constant. So P.v1=n.R.T1 P/(n.R)=T1/v1 P.v2=n.R.T2 P/(n.R)=T2/v2 T1/v1=T2/v2 v2=(T2/T1).v1 v2=volume after the transition T2=temperature after the transition T1=temperature before the transition v1=volume before the transition In this case, T2
I know why it does this. Their are air particles, when they hit the sides inside of the balloon they use that to determine the “pressure” inside of the balloon, when you cool down these particles they move slower so they don’t hit the sides as much decreasing the pressure which deflates the balloon, but when they heat up the particles move faster hitting the sides faster increases pressure which inflates the balloon. So by this logic you can blow up a balloon just by heating it up. I don’t know if it will be any different if you used iced water instead of liquid nitrogen.
It's just expansion and contraction of air present in the balloon When temperature get low in liquid nitrogen the air inside the balloon contracts and get small And when the temperature gets back to normal with the help of warm water the air inside the balloons expands and get back to normal 😊
at lower temperatures atoms comes very near and cover lesser area cause v is directly proportional to t as it reaches to room temp it occupies more area
Makes sense. The cold air compresses inside the balloon, causing it to shrivel up. As the air warms back up, it expands, returning the balloon to its previous shape/size.
Similarly, many people don't realize that propane turns into a liquid at -44°F That means if it's colder than -44°F you could open a propane tank and see the liquid inside, or even pour it out into a bucket.
If y’all don’t know what’s happening since the liquid nitrogen is cold it slows the air particles witch makes it take up less space aka pretty much deflating and since the air is warmer than the liquid nitrogen it’s warms it up and inflates
Its all just based on the universal gas equation PV = nRT; We can see that the volume V is directly proportional to the temperature T. Hence as the temperature is brought down to -196 *C, the volume is drastically decreased.
Same thing happens with your tires during winter months, to a much lesser degree of course. That's why your tire light may come on in your car in cold weather but go away after you drive a a bit and friction warms up the air in your tires
For those who ask why it’s happening, it’s because cold air are compressed and when it heat, it expense. Btw, sorry for my bad English if I made a mistake lol
Hmmm, wondering what happens when you fill them with different gasses. Propane, helium, hydrogen, nitrogen, oxygen. Would they shrink different amounts, and would they regain their size at different speeds?
Yeah bro, its was actually true, i saw this in front of my eyes. Our schools chemistry lecturer also done this This says that if the temperature decrease the volume also decreases, this is what happened to the balloons😊😊
Fun fact :- this exact process is used in rocket launching But instead of balloons its fuel. So with the help of that more fuel can be filled in a small space or vessel ❤
