Does a Vacuum Chamber Weigh Less Under Vacuum?-Mind Blown!

Рет қаралды 182,978

6 жыл бұрын

In this video I weigh the vacuum chamber when it is under vacuum to see if it weighs less without air in it. Then I weigh the chamber with pressure in it. Then, I see if objects in the vacuum chamber change weight when there is no air in the chamber! This was such a fun video to to make! I knew what would happen but it was so neat to see it in real life!

Momma O I think it's more because of the weight of the water that's still on you than the difference between air and water weight.

@neurofiedyamato8763 6 жыл бұрын

Most of the weight increase is from soaked clothes. Drench a T-shirt and pants and it feels no where near as heavy as when you come out of a pool. You just got used to the weight in water so when you get out the less buoyant air suddenly make you feel heavy. Yes the wet clothes do add a bit of weight but it isn't the major contribution to the feeling of heaviness.

@AndrewAce. 6 жыл бұрын

It's like he said; You're more buoyant in water meaning gravity doesn't effect you quite as much. After you've adjusted and then left the water however, you'll feel the full effect of gravity once more and feel heavier in contrast...

@neurofiedyamato8763 6 жыл бұрын

You can easily prove it's not mere weight of water on wet clothing. get a pair of pants and shirt. Then drench it in water. Wear it or carry it whatever, it doesn't feel nearly as heavy as coming out of a pool. Also, I know what you are trying to say, but the phrasing can lead to misunderstanding. Gravity affects you as much as out of water. The difference is that some of its downward force is canceled out by a upward buoyant force. The forces are still there so it still affects you. For gravity to affect you less, you need to be farther away from an object with mass. Same result, I know I'm being pedantic but I felt like it should be something to be cleared up. Some people might misunderstand.

@AndrewAce. 6 жыл бұрын

*Neurofied Yamato* Yes, that's what I meant. Thanks... To be more accurate: 1) The buoyant force opposing the force of gravity on your body makes you feel lighter. 2) Once you've been submerged long enough your body adjusts to this feeling. 3) After you've left the water, it takes time to readjust to supporting the full weight of your body.

Since water flows slower out of a bottle than you think due to it being a small vacuum in the bottle and the pressure outside pushing some of the water back into the bottle, does water flow faster in a vacuum chamber? I know it'll be a little hard to do it in the chamber.

@pietrayday9915 5 жыл бұрын

Thanks, Jesus - what a cool question, I've never heard of the "21 grams" thing before! Alas, the Christian doctor who conducted the experiment, Dr. Duncan MacDougall, actually ruled that possibility out, by conducting a test in which a living subject laid on the scale used in his experiments, and then exhaled and inhaled air. The air did not make any difference (and it should be noted that the exhalation of air from a corpse does not result in a vacuum inside the body, anyway.) Which leads to the curious matter of what, exactly, did account for the 21 grams in the experiment? The good doctor took care to perform the same experiment on both dogs and humans, and found that humans lost the ~21 grams of weight shortly after death, and the dogs didn't. MacDougall concluded, based on Christian philosophy, that the explanation must surely be that humans, of course, have souls, but dogs do not. But, the difference in results between humans and dogs might be the key to the explanation: when under exertion, such as running, playing, or fighting a hopeless fight for life in their dying moments, dogs pant - they can't sweat. Humans, on the other hand, can sweat, and the subjects of the experiment - suffering in their dying moments from tuberculosis, diabetes, and other ailments that might have produced copious sweating in a dying patient - likely did sweat. Sweat soaks into the hospital garments worn by the dying subjects, wicks through the fabric against the atmosphere, and evaporates. Modern researchers conclude that 21 grams of evaporated sweat might have easily have been lost by patients in the time during and following their death. Thus, evaporation of the patients' sweat is today the most popular and generous theory for the results that MacDougall measured. MacDougall's contemporaries and other critics have less kindly charged MacDougall with just plain bad science in the form of flawed experimental condition and poor sample size, or even accused him of deliberate fraud in the name of sensationalism! As near as I can tell, though, MacDougall conducted his experiments in good faith, and did his best to try to eliminate as many variables as he could, even if he might have reached the wrong conclusion, though it's only fair to note that nobody since has really made much effort to replicate the experiment since to see if the sweat theory actually holds up, or whether more extensive tests under more controlled conditions would still yield the same results MacDougall reported. Anyway, it's a curious question, and one I enjoyed researching the answer to a great deal! The easy answer is, "No, the scientist who concluded that the 21 grams must be the human soul actually ruled out the possibility that breath might account for the difference in weight!" The more difficult answer is, "No: it's probably not 21 grams worth of human breath, and probably not a human soul, either, but the experiment was flawed, it's never been conducted again under more controlled scientific conditions, and for now, it's anyone's guess what MacDougall actually measured!" Which is OK with me - I don't mind a good unanswerable mystery from time to time :)

Hey! You could have used this as an opportunity to teach Boyle's law, which can explain why most of the mass of the air was already gone by the time you were at half an atmosphere. A lot of people would expect only half the mass to be gone at half an atmosphere!

@TimpBizkit 6 жыл бұрын

The balloon kept floating for quite a while but expanded to compensate. I'm surprised it didn't burst sooner actually although technically it didn't have to withstand 1 atmosphere of pressure because the helium expanded too. When measuring the density of gas it's good to take in account the pressure because the helium will continue to float if it is allowed to expand to the pressure of the surrounding air. It would be interesting to try with a substance that to a certain extent did not allow expansion and contraction. It would be interesting to see if aerogel floats in several atmospheres of pressure, assuming it is not porous and allowing the air to come in and equalise the pressure. Maybe try argon too to see if you can float a piece of aerogel.

@The Action Lab I wonder what happens when you put hot water (already boiling) into a vacuum chamber with a thermometer?

@georgeknowles8762 6 жыл бұрын

Brad McGashette Boiling water in a vacuum. As the pressure reduces, the water will "flash off" as steam. The temperature will also drop because of the latent heat of evaporation (in reverse) has taken energy away from the liquid water. Boil a kettle in Denver (mile high) and it will boil at a lower temperature than on the coast. An observable, tabulated, and theoretically verified phenomenom used millions of times by engineers on a daily basis. To increase boiling point, increase pressure. Again, easily verified with the use of a domestic pressure cooker. Not used domestically much nowadays, but it has 3 different pressure settings, achieved by 3 different weights on a needle valve, 5, 10, and 15 psi. Put some stew in a pressure cooker and bring it to the boil, but don't take the lid off until you reduce the pressure slowly by removing the weighted needle valve. You will be cleaning stew from the kitchen ceiling for days after you've left hospital, where you were admitted after receiving 3rd degree scalds to your hands and face. I think pressure cookers are still used in commercial applications. Just checked online- domestic pressure cookers are still sold. We just don't use it in our kitchen now. I'll have to check with friends and family to see if anyone else uses one. Maybe modern ones have a safety feature to prevent lid removal under pressure. The cheap domestic pressure cooker also demonstrates how easy it is to make a pressure vessel to withstand 15psi, as in a spacecraft, suitable for use in the near vacuum of space. In this case, it's air instead of stew.

The thing with scales is that they approixmate mass based upon the force exerted on an object by gravity, there is another disconnect too because scales actually feel normal force, which is theroetically equal to force exerted by gravity. This only really matters when doing smaller measurments.

@entropia5874 6 жыл бұрын

You could consider an experiment on this: Buoyancy results from the fatc that hydrostatic pressure at the bottom of an object (upward force) is higher than at the top of the object (downward force). So if you "remove" the upward component of hydrostatic force, objects should no longer float. If you put a buoyant object at the bottom of a container, pour water and somehow manage to prevent water from getting "under" the object (probably hard to do in practice), will it no longer float? Or will it still float because the upward component of hydrostatic force is replaced by the reaction force of the bottom surface of the container? Then you could make a hole in the bottom of the container, cover it with a buoyant object, pour water and see if you can make the object stay at the bottom.

Hmm, technically one could use that to measure the pressure inside without being inside. One would have to know what the ambient pressure is and the weight it had before, therefore is would only measure relative pressure (relative to the previous pressure), or the change in pressure. But still, that would be an interesting way of measuring (or rather determining, since you don't actually measure it) the pressure. Or of course if you know the weight and pressure it had before and that it has now, you could "measure" the volume of the container...
