Chapter 1 Flashcards
Accuracy
How close an experimental measurement is to the true value
density
The mass of a substance divided by its volume
Derived unit
A metric unit that is created by adding a prefix to a base unit
Kelvin Scale
A temperature scale in which 0 degrees is the lowest possible temperature
mass
The resistance of a sample of matter to being accelerated, generally used interchangeably with weight
Precision
How close multiple measurements are to one another
standard
an object or substance that is used to check the accuracy of a measuring device
unit
A standard, defined amount that is used to express other measurements.
volume
The amount of space an object occupies
weight
the force exerted by a gravitational field on an object that is directly proportional to its mass
temperature
A measure of how hot or cold a substance is relative to another substance
heat
The energy transferred between objects because of a difference in their temperatures only
extensive property
A property, such as mass, that depends on the quantity of substance present
intensive property
A property such as density that does not depend on the quantity of substance present
uncertainity
A characteristic of every measurement that results from the inexactness of the measuring device and the need to estimate when taking a reading
