A modernized form of the metric system was internationally adopted in .2. (Circle T - F ) This measurement system, call SI, is now used by every recognized scientist worldwide.Questions 3-8 refer to the picture at the right,from p.6 in your text.3. Object #1 is a beaker with graduated markingsto approximately measure and hold liquidvolumes. What are the numbers and names oftwo other numbered items which moreaccurately measure volume?a. #b. #4. What are the numbers and names of itemswhich measurea. mass? #b. weight? #c. A scale and a balance weigh and massdifferently. Which one uses a spring?5. Which object is concerned with angles (degrees)#6 a. Which object is concerned with degrees (butnot angles)?#b. What is this metric degree?7. a. Which objects could measure the diameter of a quarter?# , #b. Which would do it more accurately? #8. (Circle T - F ) There is a measuring device shown to measure every measurable unit. (length, volume,mass, temperature, time, and angle)9. a. A meter is a little than a yard stick.b. To measure smaller objects, we divide a meter into parts for cm.c. Even smaller objects can be measured in which is 1/1000 m.

10. The distance across your fingernail is about 1 cm. What are the approximate dimensions of and audiocassette in cm. (l x w x h)?x x = c.c. (cm3)11. Your waist is about 1 meter (m) from the floor. A box which is 1 m3 would most approximately holda(bicycle - tricycle - basketball) with a little space left over.12. a. A liter is a little larger than a (pint - quart - gallon) and a little less than 3 cans of pop.b. If we divide a liter into parts, we have useful chemistry volume unit called mL.13. There is an important connection between c.c (cm3) and mL. How does 1 c.c. compare in volume to 1 mL?Your Turn: I.1 p.61. A penny diameter = mm = cm A nickel diameter = mm = cmA quarter diameter = mm = cm A dime diameter = mm = cm2. cc = mL = L = sugar cubes3 a. Only U.S. customary volume units? What are they?b. Both U.S. and S.I. units. Include volumes.4 a. One SI system advantageb. One SI system disadvantage
