  11. Graphical Techniques

  12. Rules of Significant Figures • Counting zeros • Rounding • Product/Quotient can have no more sig. Figs. Than numbers with the least sig. Figs. • Sum/Difference can have no more decimals than numbers with least decimals. • Keep at least one extra digit for intermediate calculations • Exact Numbers

  13. Rules of Significant Figures: Examples

  14. Mathcad Answers

  15. Dimensional Analysis Dimensional Analysis • Method of calculation utilizing a knowledge of units • Conversion factors => simple ratios relating two units • Desired unit = given unit  (conversion factor)

  16. Examples

  17. Density Example • The sun is estimated to have a mass of 2x1036 kg . Assuming it to be a sphere of average radius 6.96x105 km , calculate the average density of the sun in units of g cm-3 . Mathcad Soln Mathcad w Instructions

  18. Stoichiometry Example • Determine the number of hydrogen atoms present in 2.56 kg of water.

  19. Pressure Atmosphere Pressure and the Barometer • Standard atmospheric pressure = 760 mm of Hg • 1 atm = 760 mmHg = 760 torr = 101.325 kPa. Graph Demo

  22. Common Terminology • System: Part of universe being studied, set apart by definite boundaries. • Surroundings: Medium outside System. • Isolated System: No energy or matter transferred between System and Surr. • Closed System: Energy transfer between Sys. and Surr. • Open System: Energy and Matter transfers between Sys. And Surr. • Properties: Quantitative measures of physical quantities ( i.e. pressure and temperature ) Graph Demo Graphical Techniques
