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 apart that the behavior of a molecule is not influenced by the presence of other molecules-a situation encountered at low densities." I know that we can use the compressibility factor to find out if its not an idea gas or not but I am missing the specific volume. z=Pν/RT where z is the compressibility factor and ν is the specific volume. I checked the ideal gas properties of nitrogen table in my book but it doesn't include specific volume. How am I supposed to know if nitrogen at this temperature and pressure is an ideal gas or not?
