Cycle of Scientific Enterprise
tests the hypothesis and provides evidence that either supports or doesn't support the hypothesis
what is an experiment
SI unit for time
what is a second (s)
are captive zeros significant
yes
convert 54.32 C to F
what is 129.8
(9/5 x 54.32°C) + 32
the more ____________ an object has, the the more difficult it is to accelerate the object
what is inertia
predictions are made about what would happen
what is a hypothesis
SI unit for length
what is a meter (m)
are trailing zeros significant
yes, if a decimal is present
convert 78.0 F to C
what is 25.6°C
5/9 x (78°F − 32)
numerical measurement specifying the amount of inertia, which depends on how many atoms it is composed of and how massive those atoms are
what is mass
models of our best explanation to date based on facts
what is a theory
SI unit for mass
what is a kilogram (kg)
give this number in scientific notation: 5,430,000
what is 5.43x106
formula for converting C to F
what is 9/5 Tc + 32o
variable we use to quantify how much space an object takes up
what is volume
Evaluation of whether the experimental results are consistent with the initial theory
what is analysis
what does a mole measure
what is amount of substance
when should you round final answer to the same number of sig figs as the measurement with the fewest sig figs
what is multiplication/division
formula for converting F to C
what is 5/9(TF - 32o)
this formula relates to lack of error (how close it is to the true value)
what is percent difference
statements based on evidence from many experiments or observations that are correct as far as we know; they can change
what is a fact
_________ relates to lack of error (how close it is to the true value)
_________ is limited by instrument used to take measurement and indicated by number of significant figures
what is accuracy
what is precision
when should you round final answer to the same number of decimal places as the measurement with the fewest decimal places
what is addition/subtraction
Convert 391.0 K to C
what is 117.9°C
(391K − 273.15 = 117.9°C)
give the percent difference if your theoretical value is 83.5 m and your experimental value is 81.2 m
what is 2.75%
