Shrinking balloon in liquid nitrogen
液氮中的缩小气球
 |
 | Applying the ideal gas law to the gas above the liquid nitrogen in a vacuum flask suggests that the volume of a balloon placed in it would reduce to one-fourth its volume. Actually, it reduces much more than that - virtually removing all the gas in the balloon.
Why doesn't the ideal gas law apply in this case?
将理想气体定律应用于真空瓶中液氮上方的气体，暗示放入其中的气球体积会减少到其原来的四分之一。实际上，它减少得更多——几乎将气球中的所有气体都排出了。为什么在这种情况下理想气体定律不适用？ |
It is interesting to observe the amount of liquid present inside the balloon once it has been in contact with the liquid nitrogen.
观察气球接触液氮后内部所含液体的量是有趣的。
