AI Thread Summary
Electricity cannot directly replace heat to make air rise, as buoyancy relies on the temperature difference created by heated air. While electric heating elements can warm air, the fundamental principle of hot air rising due to lower density remains unchanged. The discussion highlights the importance of understanding thermodynamics and the behavior of gases. Alternative methods, such as using electric fans to create airflow, can assist in moving air but do not replicate the buoyancy effect of heated air. Overall, while electricity can heat air, it cannot replace the physical properties that cause hot air to rise.

Hello all, i was wondering this i doubt it but would it be possible to somehow replace the heat in hot air with electricity to make the air rise like it was heat but it's not? I would like to know if this is somehow possible I'm a bit of a noob on this so any help would be good thank you.

This looks a lot like your question from last November...

Thread 'Question about pressure of a liquid'

I am looking at pressure in liquids and I am testing my idea. The vertical tube is 100m, the contraption is filled with water. The vertical tube is very thin(maybe 1mm^2 cross section). The area of the base is ~100m^2. Will he top half be launched in the air if suddenly it cracked?- assuming its light enough. I want to test my idea that if I had a thin long ruber tube that I lifted up, then the pressure at "red lines" will be high and that the $force = pressure * area$ would be massive...
