This is about a group project for our science class and we've decided to do a physical model on clouds.
We could use liquid nitrogen and hot water to demonstrate the formation of the clouds and we are aware that it doesn't form like that in the nature.
I just wanted to ask, what's the pressure required for clouds to form? I found out that it's -10o C temp. but nothing about pressure (lower than normal but don't have the exact number)
Any ideas? :( I'm starting to feel pretty desperate.
Can we use the nitrogen to decrease the temperature to -10 and then pressure, and wait for liquid water to condensate?
Any kind of answer will be appreciated. Thanks :)
