Adde an exaple the tritical point removes need for tripple point

| Feb 18, 2016 at 16:44 | comment | added | Carl Witthoft | @BruceLee Interesting - so do you know of any material which acts that way? The only possibilities I see are (1) requires nonzero pressure at 0Kelvin to solidify, (2) requires nonzero pressure at 0 Kelvin to liquify. I'm not sure this is possible under various laws of physics. | |

| Feb 18, 2016 at 8:38 | comment | added | Yvan Velenik | I don't understand why is this downvoted without even leaving a comment? It is clearly not universally true, but it is at least partially correct. However, I would have added a link to the Gibbs phase rule. | |
| Feb 18, 2016 at 8:34 | comment | added | Bruce Lee | i didn't downvote... but your geometric sense is wrong, for there can be 1. closed phase boundary curves 2. parallel phase boundary curves which can lead to no triple points... | |
