If liquid nitrogen from a portable tank is poured directly into an open stainless steel container, will it vaporize immediately?
Thread Content
Liquid nitrogen needs to be filled into the stainless steel open container; it is possible to pour the liquid nitrogen directly into the container using a portable liquid nitrogen tank (just like pouring water)
It will evaporate, but not very quickly
If the tank is at a warm temperature (room temperature), that will happen; therefore, it is possible to first pre-cool it with low-temperature nitrogen before gradually filling it with liquid nitrogen~~
Using a stainless steel open-container as a vacuum jacket slows down evaporation
It’s okay; you can pour it just like boiling water. We use stainless steel thermoses to store liquid nitrogen.
Why doesn’t liquid nitrogen evaporate when it is in a room-temperature environment?
Yes, due to the large temperature difference – liquid nitrogen is at -196 degrees Celsius, so its evaporation rate is very fast~~
