For convenience, themeasuring instruments forliquids are usually cylindri-cal vessels, marked off incubic centimeters andknown as graduates. (dT) Using a large gradu-ate, determine how many cubic centimeters of water areneeded to fill an ordinary quart measure. (To be done in groups of four students unless otherwise directedby the instructor.) (/) Using a small graduate, find the capacity in cubiccentimeters of the small bottle furnished you. Similarly determine the capacity of an ordinary drink-ing tumbler. Units of Weight. — The weight of a cubic centimeterof water at its maximum density (4° C.) is taken as theunit of weight, the gram. 1000 grams make a kilogram, a weight used for measur-ing large Fig. 5. Dissected Liter Block. PROPERTIES OF MATERIALS 21 (f) Using a platform balance, find the weight in gramsof your laboratory note-book. Record. (g*) Determine how many grams are needed to counter-balance an ordinary pound weight. Record. Tables for the calculated results should be placed atthe top of the right-hand page of the note-book, and thecalculations worked out just beneath them. Express the number of cubic centimeters found in (c?)as the decimal part of a liter. Using this number, calcu-late the equivalent of a liter in quarts, carrying the resultto two decimal places. Calculate from the comparison of weights found in (</),the equivalent of a kilogram in pounds and tenths of apound. Calculated Results 1 liter qts. 1 kilogram lbs. Discussion: In what respects was the convenience of the MetricSystem shown in your measurements? Place the answerto this question on the right-hand page of th
