Suppose I have a sealed container of fixed volume containing 3/4 air and 1/4 of some liquid by volume at room temperature (22C). I wish to boil the liquid by applying external heat.
As I apply heat to the container, the pressure inside the container will rise, which will change the boiling point of the liquid. How do I calculate the temperature needed to boil the liquid under these conditions?
If it matters, we can assume any boiling point in the range of Acetone (50C) to Ethyl Bromide (38C)
FWIW, I'm playing with the idea of building a heat engine based on low temperature differentials and operating at near room temperature. Since this would be a hobby thing, the working fluid needs to be affordable, available, not encumbered by heavy regulation, and not TOO nasty to work with.
Thanks In Advance.
