Question | Answer |
---|---|
Mass: | The amount of matter in a substance. |
Gram: | Basic unit of mass. |
What are examples of units of metric mass? | Kilograms, hectograms, decagrams, grams, decigrams, centigrams, milligrams. |
What are the labels of units of metric mass? | kg, hg, dag, g, dg, cg, mg. |
What are the common units of mass in the English/standard system? | ounces, pounds, tons. |
What are the labels for English mass? | oz, lbs, T (capital) |
How is mass measured? | By using a balance. |
Volume: | The amount of space a substance takes up. |
Liter: | The basic unit of volume. |
What are examples of units of fluid metric volume? | kilometers, hectoliters, decaliters, liters, deciliters, centiliters, milliliters. |
What are the labels of units of fluid metric volume? | kL, hL, daL, L, dL, cL, mL. |
What are other units of fluid volume In the English system? | fluid oz., cups, pints, quarts, gallons. |
What are the labels of the other units of fluid volume? | fl.oz., c., pts., qts., gals. |
What is liquid or fluid volume measured with? | a graduate. |
What are examples of solid metric/English volume? | any distance unit with the word cubic in front of it. (ie cubic meter, cubic centimeter) |
Why do certain labels have to be cubed? | the solid volume of a rectangular object is 3 dimensional and measures 3 distances and needs a ruler to measure it. |
What are labels for solid metric volume? | km(3), hm(3), dam(3), m(3), dm(3), cm(3), mm(3). |
What are labels for solid English volume? | in(3), ft(3), yds(3), mi(3). |
Distance: | The amount of separation between two points. |
Meter: | the basic unit of distance. |
What are examples of units of metric distance? | kilometers, hectometers, decameters, meter, decimeter, centimeter, millimeter. |
What are the labels of distance? | km, hm, dam, m, dm, cm, mm. |
What are examples of units of English distance? | Inches, feet, yards, miles. |
What are labels of English distance? | in, ft, yds, mi. |
What is distance measured with? | Ruler or meter stick. |
Density: | The amount of mass in a certain volume. |
What is the formula for density? | D=M divided by V. |
Why does density have a double unit label? | it involves two different types of units (mass and volume) |
Examples of labels for density: | any mas unit divided by a volume unit (g/cc, g/mL, kg/m(3) |
What is step one of determining the increments? | Subtract the difference between any two numbers on the graduate and write that number inside the division box. |
What is the second step of determining the increments? | count the number of lines between the numbers. It will always be 5 or 10. Put that number outside of the division box. |
What is step three of determining the increment? | Divide. The quotient is the increment you have to know this to read the graduate correctly. |
Measurement: | comparing something to a known standard. |
What is the metric system abbreviation? | S.I= System International. |
Weight: | the measurement of the pull of gravity on a substance. |
What are all the prefix's? | kilo, hecta, deca, base, deci, centi, mili. |
What are the values of each of the prefix's? | 1,000, 100, 10, 1, .1, .01, .001. |
Liquid displacement volume: | used to measure the volume of irregularly shaped objects. |
what is the label for liquid displacement? | cc, or cm cubed. |
How do you read a graduate? | read below the meniscus. |
How do you find the mass of a liquid? | weigh the graduate by itself, put 10 mL of water, find the mass of the graduate and liquid together, subtract the difference. |
How do you find the volume of an irregular object? | Fill a graduate with water higher then the object, read the level, put the object in the water, read the level again and subtract the difference. |
What also measures distance? | a trundle wheel. |
