A football field is 120 yards by 53.333 yards. What is the area of the football field
in acres if 1 acre=43560 ft2? Use correct significant figures when answering this
question.
Type answer: - ANS - 1.3
\Based on everyday experience, state (in words) the relationship between tire
pressure and temperature. Look at the data and see if the numbers support your
statement. - ANS - Temperature and pressure are directly proportional. This
means that when the temperature increases the tire pressure will increase. When
the pressure decreases the temperature will also decrease. This proportionality is
seen in tires. A tire expands when the temperature increases, and when the
temperature decreases a tire will deflate. The numbers in the data generally
support this theory. When the temperature increases the tire pressure increases,
and when the temperature decreases the pressure decreases.
\Compare the calculated pressure to the two visually interpolated values (Steps 2
and 6a). Briefly discuss any discrepancies. - ANS - There are discrepancies
between the calculated and visually interpolated values, because the calculated
value is more accurate. The visually interpolated value was based on what we
perceived was the correct value. The calculated value is the correct value based
on the equation of the line.
\Compare the calculated temperature to the two visually interpolated values
(Steps 2 and 7a). Briefly discuss any discrepancies. - ANS - The calculated
temperature is more accurate than the visually interpolated values. The
calculated data was based on the best-fit equation that was found for the graph.
The interpolated values is an estimated value that was determined by eyeballing
the graph and estimating where the point would be plotted.
\Determine the relative order of the metric prefixes of kilo-, micro-, centi-, and
milli-. - ANS - For the same base unit, micro- is less than milli-, which is less than
centi-, which is less than kilo-
\Determine where each type of cleaning solution should be discarded after use. -
ANS - Solvent used to rinse chemicals out of a beaker
→ waste container
Water used to rinse detergent out of a flask
→ sink
Acid solution used to clean a crucible
