by Gary H Member since:November 16, 2007Total points:24,578 (Level 6)If you reduce the pressure on water, the boiling point temperature goes down. This is why some cooking recipes are a little different in Denver CO than they are at sea level. Higher altitude lowers the boiling point of water. Reverse is lso true, if you pressurize the system, like a pressure cooker on the stove, the boiling point goes up. If the atmospheric pressure goes down far enough, the water in the astronaut's body starts to boil.

Open Question: why did Einstein disagree with Niels Bhor during their debates about Quantum Mechanics?
Open Question: Can explosive events occur in the sky can during the formation of a star?
A star forms half way across the galaxy. No one may be able to even notice, since the process happens over millions of years. I would have to say that you're not going to see "rockets red glare" and "bombs bursting in air" unless you're willing to sit and wait over a very long time span.
Open Question: Taking Calculus III during summer or fall?
Ryan Member since:December 12, 2007Total points:15,067 (Level 6)I want to know if its better to take it during the summer or the fall year. And how rigorous would the course be on a scale of 1-10 if you did pretty decent (mostly B's and A's) on calc I and II?Answer QuestionBe the first to answer this question.
