B How to measure the area of a Clapeyron diagram (pV diagram)?

  1. Dec 14, 2016 #1
    The question is in the title. However my mathematical ability is limited as I am a high school student.

    Thank you in advance

    Many different methods . Post the diagram and tell us where it originates .

    Cut out the area with a scissors and weigh it on a sensitive balance. Then cut out a known rectangular area of the paper and weigh it to calibrate the paper.

    Thank you I will try this, I do not know if I have access to a sensitive enough balance.

    You're a high school student, but some high school students have had calculus. Have you had integral calculus yet?

    Trace the shape onto squared graph paper and count the squares. You'll find that most fractions of a square can readily be paired with another to form the equivalent of one whole square, then use your best estimate for the area of each of those remaining.

    And do you know the P-V equations for each "side" of the figure in your diagram?
