absolute type
the zero point on the kelvin temp. scale, equivalent to -273 celsius; all molecular motion theoretically stops at this temp.
accepted value
a quantity used by general agreement of what is being measured.
accuracy
the closeness of a measurement to the measurement to the true value of what is beng measured.
celsius scale
the temp scale in which the freezing point of water is 0 celsius, boiling point is 100 celsius
density
the ratio of the mass of an object to its volume
error
the difference between the accepted value and the experimental value.
gram
a metric mass unit equal to the mass of 1 cm3 of water at 4 celsius
hydrometer
a device used to measure the specific gravity of a liquid
international system of units
the revised version of he metric system , adopted by international agreement in 1960
kelvin scale
the temp scale inn which the freezing pont of water is 273 K and the boiling pt is 373 K; 0 K is the absolute zero
kilogram
the mass of one liter of water at 4 celsius; it is the base unit of mass in SI
liter
the volume of a cube measuring 10 centimeters on each edge (1000 cm3) ; it s the common unprefixed unit of vlume in the metric system.
meter
the base unit of lenght in SI
percent error
the percent that a measured value differs from the accepted value
precision
describes the closeness or reproductability of a set of measurements taken under he same conditions
qualitative measurement
a measurement that gives descriptive nonnumeric results
quantitative measurements
a measurement that gives definate, usually numeric results
scientifc notation
expression of numbers in the form n x 10n (little squared n) where n is greater than or equal to one and less than 10 and n is an interger
signifcant figure
all the digits that can be known presicely in a measurement, plus a last estimated digit
specific gravity
the ratio of density of a substance to that of a standard substance(usually water)
temperature
a measure of the average kinetic energy of particles in matter; temperature determines the direction of heat transfer
volume
the space occupied by a sample of matter
weight
force that measures the pull of gravity on a given mass
