    Is nitrogen at 27˚C and 100 kPa an ideal gas?

    I understand that I could assume that nitrogen is an ideal gas at that temperature and pressure but I was having trouble understanding what makes a gas ideal in the first place. Only thing I knew that I could relate to this problem was that there is a range in the compressiblity factor where the...

    Is nitrogen at 27˚C and 100 kPa an ideal gas?

    I wanted to understand the general idea behind this question instead of finding the answer from a specific scenario if that makes sense.

    Is nitrogen at 27˚C and 100 kPa an ideal gas?

    I see it now, with Pr and Tr, I can find what z is. And I can find Pr and Tr with the given information. Thank you for your help, I understand this much better now.

    Is nitrogen at 27˚C and 100 kPa an ideal gas?

    Since the compressibilty factor is a unique function of reduced pressure and reduced temperature, that is the only information required for me to find z. Correct?

    Is nitrogen at 27˚C and 100 kPa an ideal gas?

    I would love to know how else to solve this problem.

    Is nitrogen at 27˚C and 100 kPa an ideal gas?

    If fluids compared at reduced pressure and reduced temperature have about the same compressibility factor. I would have to find the actual pressure and actual temperature of the fluid (lets say He) I am comparing it to, then find out if helium at that pressure and temperature is an ideal-gas or...

    Is nitrogen at 27˚C and 100 kPa an ideal gas?

    Specific volume is the inverse of density. However, as you know, density changes with temperature. So I would need the density or specific volume at 27°C but I cannot find it in my ideal-gas properties for nitrogen table and cannot find it online.

    Is nitrogen at 27˚C and 100 kPa an ideal gas?

    I don't understand ideal gases conceptually well enough to get any useful information out of that. I already looked at that before I posted here. But I believe I might have an answer for it. Since we need two independent properties to identify the state of the system, and pressure and...

    Is nitrogen at 27˚C and 100 kPa an ideal gas?

    Hello everyone. I stumbled across a problem while studying for my exam that I cannot confidently answer. Can we assume nitrogen at the temperature of 27˚C and the pressure of 100 kPa an ideal gas? Justify your answer. The definition of an ideal gas is "...a gas whose molecules are spaced far...

    Integral of x^e - Solving the Problem

    I'm practicing integrals right now and came up on a question I have not seen before nor can I find online. Integral from 0 to 1 of (x^e + e^x) dx I'm stumped on x^e.
