  1. Reading a Vernier Caliper

  2. Ways to use a Vernier • There are three ways to use a Vernier caliper • Measure width of an object • Measure width of a gap • Distance between two surfaces

  3. Width of an object

  4. Width of a Gap

  5. Distance between two surfaces

  6. How to read a Vernier Caliper • The Vernier Caliper is scaled to hundredths of a centimeter. • Tenths of a centimeter are tick-marked onthe scale upper scale. • .Hundredths of a centimeter are markedon the lower scale.

  7. How to read a Vernier Caliper • Estimated digit is hundredth of a centimeter. • The lower scale, only one line “lines up” with the upper scale. • This is your tenths ofmillimeter digit.

  8. How to read a Vernier Caliper (Example)‏ • Read this caliper: • How many centimeters?

  9. How to read a Vernier Caliper (Example)‏ • Read this caliper: • How many centimeters? 2 • How many tenths of a centimeter?

  10. How to read a Vernier Caliper (Example)‏ • Read this caliper: • How many centimeters? 2 • How many tenths of a centimeter? 1

  11. How to read a Vernier Caliper (Example)‏ • Read this caliper: • How many centimeters? 2 • How many tenths of a centimeter? 1 • How many hundredths?

  12. How to read a Vernier Caliper (Example)‏ • Read this caliper: • How many centimeters? 2 • How many tenths of a centimeter? 1 • How many hundredths? 9

  13. How to read a Vernier Caliper (Example)‏ • Read this caliper: • 2.19 cm

  14. How to read a Vernier Caliper (Another Example)‏

  15. How to read a Vernier Caliper (Another Example)‏ • How many centimeters? • How many tenths of a centimeter? • How many hundredths?

  16. How to read a Vernier Caliper (Another Example)‏ • How many centimeters? 2 • How many tenths of a centimeter? 6 • How many hundredths? 3

  17. Graphing Data • If you have data for quantities K and L, and you are instructed to graph “K vs. L” What would that look like?

  18. Graphing Data • If you have data for quantities K and L, and you are instructed to graph “K vs. L” What would that look like?

  19. Graphing for slope • If you are told to construct a graph with a slope equal to some quantity what should you do?

  20. Graphing for slope • If you are told to construct a graph with a slope equal to some quantity what should you do? • Find an equation relating the data you have taken and that quantity.

  21. Graphing for slope • If you are told to construct a graph with a slope equal to some quantity what should you do? • Find an equation relating the data you have taken and that quantity. • Solve the equation for that quantity.

  22. Graphing for slope • If you are told to construct a graph with a slope equal to some quantity what should you do? • Find an equation relating the data you have taken and that quantity. • Solve the equation for that quantity. • The numerator of your equation should be the vertical axis, and the denominator should be the horizontal axis.

  23. Example • You’re in a chemistry class, and you’re doing a lab on the ideal gas. You have data for P, V, n and T. You are told to construct a graph with a slope of R. What should you do?
