    Prove that If A,B are 3x3 tensors, then the matrix C=AB is also a tensor

    I try to solve but i have 1 step in the solution that I don't understand who to solve. Below in the attach files you can see my solution, the step that I didn't make to prove Marked with a question mark. thanks for your helps (:

    Engineering Thermal expansion coefficient calculation — where is my mistake?

    Hello everyone, Once I got through the VDW state equation I came to the expression of the thermal expansion coefficient. When I place the values I get an illogical answer. Is there a problem with the units? (Please ignore the values) Thanks. This is the unit equation I get to and get stuck:

    I saw wikipedia page, but the equation not clear. I think some sign is missing. from wikipedia:

    Engineering Spinodal and Isotherms graph on P-V diagram

    I try to find the reduce form of Redlich Kwong equation. you have the reduce form for this EOS? or some good book/ article that show how to develop from original form to the reduce form.

    Engineering Spinodal and Isotherms graph on P-V diagram

    Thank, I want to find a development for a state equation to get points on the spinodal for fluid (except a VDW state equation).

    Engineering Spinodal and Isotherms graph on P-V diagram

    Thank for the answer. Besides Van Der Waals, do you have a suggestion for another equation of state that is suitable for fluid?

    Engineering Spinodal and Isotherms graph on P-V diagram

    Hey guys, During my work I have to show on a P-V diagram certain points on the spinodal for water. How do I draw the spinodel and isothermal lines on a diagram (for example in Excel)? Is it something that I need to calculate? I'm lost on this, I did not find anything relevant on the internet...
