Guest Aragorn992 Posted October 13, 2004 Posted October 13, 2004 I have a question (and it probably sounds really stupid), A closed vessel containing pure O2 has a tempreature of 20 degrees © and a pressure of 3000 psi. If it is heated to 800 degrees © what is the change in pressure and how do you work it out? My Dad wants to know this for where he works, hes a welder / engineer by trade and apparently they're creating some kind of vessel thats going to do this.
swansont Posted October 14, 2004 Posted October 14, 2004 For an ideal gas, PV=nRT Oxygen isn't ideal, but it will give you an idea. T must be in Kelvin. A better value can be found using this formula.
