The triple point for water is 0.01 °C which is just a tiny bit above the freezing temperature (0 °C or 32 °F). The people posting these videos attempting to melt this snow are doing so indoors. It seems doubtful that they have their indoor temperature set at water's freezing point. The triple point can vary due to atmospheric pressure. For example, water boils at 212 degrees F at sea level. That same pot of water will boil at 150 degrees F on the top of Mt. Everest due to the lower air pressure. The atmospheric pressure can also impact at which temperature ice can undergo sublimation and turn into vapour without being liquid first. I'm seeing similar videos from various parts of the country. The first one was actually from Michigan. The second was from Atlanta and I've seen one from NYC. What are the chances of these three places all having the same atmospheric pressure to allow snow to undergo sublimation indoors? I'm not saying that couldn't be the explanation. I'm just saying it leaves room for even more questions. It also doesn't explain the smell of burning plastic that the people are reporting unless they're lying about that. Here's a video from someone in NY: NYC Brooklyn snow it turns black! - YouTube |
