Let's say that I put a tea infuser full of high-salt and/or high-sugar content, into a tea pot full of fresh water. I know that the salt and/or sugar will move from the infuser to the tea pot until their salt/sugar levels equalize.
Does the force, the pressure, which moves the water, have a name?
I thought about osmotic pressure, but I think that's just for salt? The system is also trending towards homeostasis, but that's a state, not a force. So, I'm not sure what to call this.
