... Physics Lab #1 Kris Wong 12TB Data Analysis According to Physics: Principles with Applications, the value of 0 Kelvin is -273.15 ?C. It also states that Volume/Temperature is constant (Charles Law). Mathematically Calculation of errors: ?0 = V0/[(V80-V25)/(80-25)] Maximum % error in Intercept on volume axis = 0.05/24.9 = 0.2% Maximum % error in volume change = 2*0.05/(32.0-27.2) = 2.1% Maximum % error in temperature change = 2*0.2/(80-25) = 0.7% Maximum % error in Intercept on temperature axis = 0.2% + 2.1% + 0.7% = 3.0% Maximum error in Intercept on temperature axis = 3.0% *283.3 = 8.5 Calculation of Kelvin: According to Charles Law, Volume/Temperature should be constant According to the formula generated from the line of best fit on the graph: Volume (ml) = 0.0875 Temperature (?C) + 24.966 Temperature = [Volume - 24.966] *11.429 = [0-24.966] *11.429(?C) = - 285.3 (?C) 0 Volume is reached at 0 Kelvin, Therefore 0 Kelvin = -285.3 ? 8.5 (?C) Graphically Plotting of errors: From the slope lines on graph 1.4, Maximum %
