Thanks for the prompt replies.
However, it seems that the premise of my question is faulty.
I'm more interested in how much pressure would be acting upon the container due to the heating... How would that be calculated?
Also, how would the behaviour change if say, instead of just...
I think that it's surface tension that's keeping up the needle, regardless if it is waxed or not.
As long as the needle isn't submerged in water, it should be able to float.
I have a question regarding the calculation of pressure. Not quite homework but just curious on how things work.
If I had an enclosed 18 mL (1 mol H2O) container that is indestructible/incompressible filled with water, and boil it so that all the water turns into water vapour, I get 22.4 L...
