Finding Mathematical Relationships Using Graphical Method: Linear Fit and Curve Fit Problem number X Problem number Problem number X Y Y Y Note: Indicate if n is negative. If it is positive, NO NEED TO USE THE + SIGN. Problem Slope (m) from Equation Solve for " Final equation number Linear Fit or (A) (using x, y, & k) (Show all calculations for k (x, y, and from Curve fit of the Final using the original data value of k) Linear Graph pairs). Calculated k must be the same as the slope (mor 16.1 y=k/x? Example #1 y=16/ k=yox k=(4,2)=16 k=(1X4)' = 16 Note: Round off the k to the nearest whole number, unless it is less than 1. Slope, m or A is the k in the equation. Linear Fit; Indicate which process you used (mark X): Curve Fit Part III. Boyle's Law: Pressure (P') - Volume (V) Relationship in Gases DATA SET Slope (m or A) from the Linear Fit or Curve Fit: Mathematical relationship between P and V (from the curve fit or linear fit graphical analysis): Indicate which process you used (mark X): Linear Fit; Curve Fit Volume (mL) Pressure (kPa) Constant, k (P/V or P.V)' Average k (What is the unit of ?
