van der Waal equation

You need to demonstrate when the van der Waal equation is needed and the ideal gas law equation doesn’t provide satisfactory results.
Requirements: text must be typed and you have to foot note any source you used, you can hand write any equations or calculations
Due: December 5
In the past people have used four examples, two van der Waal equations and two ideal gas equations, one set when they match and one set when they don’t, but you don’t have to restrict yourself to this idea.
This needs to be your own work, don’t copy some website. Be creative and play to your strengths. Use a descriptive paragraph(s) to describe what your calculations mean. There is no set grading scale, in the past people have earned from 0 points to 14 or so (10 points would be 1 letter grade on a test). This semester any copying from a website will earn negative points so the range is from -10 to 14 or so. If you use help from an outside source you need to cite them.
