1

Accuracy

How close an experimental measurement is to the true value

2

density

The mass of a substance divided by its volume

3

Derived unit

A metric unit that is created by adding a prefix to a base unit

4

Kelvin Scale

A temperature scale in which 0 degrees is the lowest possible temperature

5

mass

The resistance of a sample of matter to being accelerated, generally used interchangeably with weight

6

Precision

How close multiple measurements are to one another

7

standard

an object or substance that is used to check the accuracy of a measuring device

8

unit

A standard, defined amount that is used to express other measurements.

9

volume

The amount of space an object occupies

10

weight

the force exerted by a gravitational field on an object that is directly proportional to its mass

11

temperature

A measure of how hot or cold a substance is relative to another substance

12

heat

The energy transferred between objects because of a difference in their temperatures only

13

extensive property

A property, such as mass, that depends on the quantity of substance present

14

intensive property

A property such as density that does not depend on the quantity of substance present

15

uncertainity

A characteristic of every measurement that results from the inexactness of the measuring device and the need to estimate when taking a reading
