a quantitative comparison of an object’s physical quantity that involves a number and a unit.

Measurement

the magnitude of a physical quantity that may vary as a nonstandard unit or is definite as a standard unit.

Unit

an ancient system of measurement is based on the human body parts to solve practical problems. example: —3

NONSTANDARD UNITS OF MEASUREMENTS dangkal,dipa, salop

length of a forefinger

timuro

breadth of a finger

dali

width of a palm

dangkal or dama

length of a foot

talampakan

a single stride

hakbang

a handful (used to measure the amoung of graisn such as corns and rice)

dakot

a container (used to measure the amount of harvested mangoes, tomatoes, and salt)

kaing

a container (used to measure the amount of rice)

salop o kaban

a jar (used to mesdure the amount of liquids such as tuba and vinegar)

gusi

a scoop (water)

salok

A system of weighs and measures that was once the de facto standard throughout much of the world.

English System

The SI is an acronym for — that was created during the 1960s.

Système international d’unités (International System of Units)

The International System of Units was based on the — system.

metric or decimal

The metric system branched into two—the —3 and the —3 systems of measurement while the SI came up with base units. Thus, each physical quantity (i.e., fundamental quantity, derived quantity) in SI has units that vary by multiples of 10 (i.e., as indicated by the prefix) from a base unit.

meter, kilogram, second (MKS) centimeter, gram, second (CGS)

are the fundamental units of measurement from which other units can be derived.

Base units

a unit derived from two or more base units.

derived unit

Generally, derived quantities are combinations of — quantities. For instance, when a unit of length (l) is multiplied by another unit of length, it would give the derived quantity called —

fundamental area (A).

is a mathematical statement of two equivalent measurements of different units that can be expressed in fraction form (i.e., the value given at the numerator is equal to the value given in the denominator).

Conversion Factor

is the quantitative measure of the hotness or coldness of matter.

Temperature (T)

Temperature scales:

the Celsius (°C) scale, the Fahrenheit (°F) scale the Kelvin (K) scale the Rankine (R) scale

proposed the use of the Fahrenheit scale.

Daniel Gabriel Farenheit

It has no absolute zero.

Farenhei5

A — temperature does not imply the absence of heat or kinetic energy in a matter.

0°F

The negative reading in the thermometer indicates that there is a — but that it is below 0°F.

presence of heat

during the 1740s He introduced Celsius scale.

Anders Celsius (1701–1744)

Phase transitions of water molecules are often linked with three particular measurements in this scale.

Celsius

At — water molecules have zero kinetic energy and are at their most condensed form.

–273°C

Upon reaching 0°C, water molecules in three different phases (i.e., solid, liquid, gas) coexist. This temperature is called the — .

triple point of water

Last, pure water at an environment with standard pressure (i.e., 1 atm) boils at —

100°C.

—, who was also known as — - Kelvin scale

William Thomson Lord Kelvin

To increase the level of confidence on the results of an experiment, measurements are done for at least three trials. Uncertainty is associated with the following:

(1)the measuring instrument, (2) external factors such as temperature, pressure, and location where the measurement is made, and (3) the skill of the person who took the measurement.

is a qualitative term used in determining the degree of conformity of a test result to a true or accepted value.

Accuracy

, also known as average, is the quotient of the summation of all data and the number of data involved.

Mean (X)

The closer is the mean to the accepted value (i.e., 2 mg Na), the higher is the — of the data.

accuracy

refers to the absolute value of the difference between the theoretical value (i.e., the accepted value) and experimental value (i.e., usually the average value).

Error

the consistency of achieving the same results

PRECISION -

- simplified expression for a very large or small number
