13·19 days agoI had to study properties of metal for an engineering class. There was no elastic deformation that I remember, unless you pass the materials elastic limit. Important concepts to be clear about. You don’t want something plastic if you need elastic.

110·19 days agoIts not deforming at all though. Its compressing and decompressing, like a spring. Plastic is plastic, elastic is elastic. You can’t say “this plastic is elastic”, its a different property altogether.

33·19 days agoExcept, what they’re describing seems to be elastic, not plastic. Plastic deformation is permenant.
When water flashes to steam, it expands instantly to 1700 times its liquid volume. A single drop of water will explode when it comes into contact with strong acid, splashing the acid. The acid boils the drop of water instantly, from a liquid it expands as vapor explosively.
If you add water to acid, you get a bleve. It’s exothermic, the water flashes into steam and the acid can spatter from the explosion. I think thats right. I used to mix acid and water all the time. Ammonia and water is highly reactive as well, although NH3 is a gas. Really dangerous stuff.
