4) ( 20 points) The area of a triangle (A) is (bh)/2, the perimeter (P) is b+c+d. The values of c,d,b and h are as follows: 3.0,4.5,6.0, and 2.7cm, respectively. Compute the values for the following: (A/b)h,(A/h)b,(P/b)c,d,(h/b)A (Comment on the sign of the last term) (b) Knowing that (A/b)P is 0.25cm, use the appropriate conversion formula to compute the value for (h/b)P 5) (20 points) The following is a diagram for PV vs. P for three real gases A,B, and C at T1. Answer the following questions: a) At what condition(s) on the graph can the term PV be used as indication for T1 ? Briefly explaingyour answer b) How does the graph of PV vs. P for the same three gases look like at temperature T2 where T2>T1
