Question

part b true - false
classify each of these statements as always true, at; sometimes true, st; or never true, nt.
nt 11. the si base unit of mass is the milliliter.
nt 12. a decigram is 100 times smaller than a gram.
at 13. the si unit of volume is derived from the unit of length.
nt 14. there are six basic si units of measurement.
part c matching
match each description in column b to the correct term in column a.
column a

1. kelvin scale
2. international system of units (si)
3. temperature
4. meter
5. calorie
6. celsius scale
7. liter
8. joule
9. weight
10. absolute zero
11. kilogram
12. gram
13. energy

column b
a. quantity of heat that raises the temperature of 1 g of pure water by 1°c.
b. the capacity to do work or to produce heat
c. the si unit of energy
d. non - si unit of volume
e. standardized system of measurement based on the metric system
f. mass unit commonly used in chemistry
g. the si unit of length
h. force that measures the pull of gravity on a given mass
i. zero point on the kelvin scale equal to - 273.15°c
j. si base unit of mass
k. temperature scale on which the freezing point of water is 273.15° and its boiling point is 373.15°
l. temperature scale that sets the freezing point of water at 0° and its boiling point at 100°
m. measure of how hot or cold an object is

Explanation:

1. The SI base - unit of mass is the kilogram, not the milliliter (which is a volume unit), so false.
2. A decigram is 0.1 grams, so it is 10 times smaller than a gram, not 100 times, so false.
3. The SI unit of volume (cubic meter) is derived from the unit of length (meter), so true.
4. There are seven basic SI units of measurement (length - meter, mass - kilogram, time - second, electric current - ampere, thermodynamic temperature - kelvin, amount of substance - mole, luminous intensity - candela), not six, so false.

For matching:

1. A calorie is the quantity of heat that raises the temperature of 1 g of pure water by 1°C, so match with a.
2. The Celsius scale sets the freezing point of water at 0° and its boiling point at 100°, so match with l.
3. A liter is a non - SI unit of volume, so match with d.
4. A joule is the SI unit of energy, so match with c.
5. Weight is the force that measures the pull of gravity on a given mass, so match with h.
6. A kilogram is the SI base unit of mass, so match with j.
7. A gram is a mass unit commonly used in chemistry, so match with f.
8. Energy is the capacity to do work or to produce heat, so match with b.

Answer:

1. False
2. False
3. True
4. False
5. a
6. l
7. d
8. c
9. h
10. j
11. f
12. b
