With certain criteria established by the agency, the specific word will be selected to be new word added to the new version of KBBI. He also said that new loan words and/or slangs that become too frequently used, widespread, and eventually being commonly used in daily conversations may be considered to be added in the future KBBI.

In ancient Greek medicine, each of the four humours became associated with an element. Blood was the humor identified with air, since both were hot and wet. Other things associated with air and blood in ancient and medieval medicine included the season of spring, since it increased the qualities of heat and moisture; the sanguine temperament (of a person dominated by the blood humour ...
Some of the old spellings (which were derived from Dutch orthography) do survive in proper names; for example, the name of a former president of Indonesia is still sometimes written Soeharto, and the central Java city of Yogyakarta is sometimes written Jogjakarta. In time, the spelling system is further updated and the latest update of ...
The atmosphere of Earth is composed of nitrogen (78%), oxygen (21%), argon (0.9%), carbon dioxide (0.04%) and trace gases. [2] Most organisms use oxygen for respiration ; lightning and bacteria perform nitrogen fixation which produces ammonia that is used to make nucleotides and amino acids ; plants , algae , and cyanobacteria use carbon ...
The average molar mass of air (approx. 78% nitrogen, N 2; 21% oxygen, O 2; 1% other gases) is 28.57 g/mol at standard temperature and pressure . Obeying Avogadro's Law and the ideal gas law, moist air will have a lower density than dry air. At max. saturation (i. e. rel. humidity = 100% at 0 °C) the density will go down to 28.51 g/mol.
Air density, like air pressure, decreases with increasing altitude. It also changes with variations in atmospheric pressure, temperature and humidity. At 101.325 kPa (abs) and 20 °C (68 °F), air has a density of approximately 1.204 kg/m 3 (0.0752 lb/cu ft), according to the International Standard Atmosphere (ISA).
Air is the name given to the atmosphere of Earth. Air on Earth is primarily composed of 21% Oxygen and 78% Nitrogen . 1% of the other gasses are a mix of carbon dioxide , neon , hydrogen , etc.
An air quality index (AQI) is an indicator developed by government agencies [1] to communicate to the public how polluted the air currently is or how polluted it is forecast to become. [2] [3] As air pollution levels rise, so does the AQI, along with the associated public health risk. Children, the elderly and individuals with respiratory or ...
