 | | Hot Paper?
|
| Thanks to Ray Bradbury, we all know the combustion point of (at least some kinds of) paper. What would happen if you had a sheet of paper in a vacuum and heated it to 500 degrees F? Dave! (24 years ago, 27-Nov-00, to lugnet.off-topic.geek)

If you heated it quickly, it might char a bit (using oxygen trapped within the paper interstices) but I would expect that in most cases it (...) (24 years ago, 27-Nov-00, to lugnet.off-topic.geek)

For that matter, even in its approximate vacuum, the (...) (24 years ago, 28-Nov-00, to lugnet.off-topic.geek)

To keep their surface temperature within bounds, by allowing the (...) (24 years ago, 28-Nov-00, to lugnet.off-topic.geek)

I could be misremembering, maybe LDEF only had metal and plastic panels. But there were over 500 of (...) (24 years ago, 28-Nov-00, to lugnet.off-topic.geek)
