Talk:vacuum
Latest comment: 12 years ago by SemperBlotto
The plural can be vacuums or vacua, but I don't know how to change this.
Is it correct to use vacuum for underpressure just below atmosheric pressure? I have seen it writing but it is far away from the original definition. — This comment was unsigned.
- I wouldn't have thought so. But if you can provide evidence of this actual use, then we would include it in our definition. SemperBlotto 12:27, 30 December 2011 (UTC)
