water loss mL DATA ANALYSIS AND FOLLow-UP QUESTIONS A. Exercise 1: Rate of Transpiration value. Record the weight (w and area (A) of the four leaves chosen to calculate the calibration Record the weights (w, and (w, of the first and second set of leaves removed, respectively. Now, calculate a \"calibration value\" that tells how many cm there are gram leaf This ap- proach makes the assumption that all leaves have the same texture and thickness so that one cm leaf weighs the same matter from which leaf it is taken. cm3/g w, by the value of Aw determined above to obtain the combined area of the first batch of leaves removed. Total area of first batch of detached leaves w... cm

Solution

CircleArea = pi*rr

                  = pi*4*4 = 50.26

SquareArea = hh

                   = 5.65*5.65 = 32

Area of two leaves = circle area-square area

                               = 50.26-32 = 18.26

Area of two leaves = Area of two leaves*2

                               = 18.26*2 = 36.5 sq.units

A/W = 36.5/4

        = 9.125 cm²/g

W₁*A/W = 4*9.125

                = 36.5 cm²
