Partial Pressures and Depth Question

And the higher the altitude (with lower atmospheric pressure) the lower the temperature it takes to reach a boil

With the result that you need to cook wet things longer at high altitudes. My late father told me that as a child living in a Hoboken tenement he would read the high altitude cooking instructions on some packaged foods and dream of life in the mountains. He managed to retire to Wyoming so got to put those instructions to good use.

If you want to observe gas bubble formation firsthand without getting soda all over your arm, all you need to do is heat up a pot of water. A fluid's ability to hold dissolved gas diminishes as its temperature increases. At a high enough temperature, but still short of the boiling point, the gases will start to come out of the water in the form of bubbles that spontaneously appear at scratches or pits at the bottom of the pot.

Edit: I went ahead and did this myself. It's kind of fascinating.
