"The scientific method is a body of techniques for investigating phenomena, acquiring new knowledge, or correcting and integrating previous knowledge. To be termed scientific, a method of inquiry must be based on empirical and measurable evidence subject to specific principles of reasoning. ...
Four essential elements of the scientific method are iterations, recursions, interleavings, or orderings of the following:
(1) Characterizations (observations, definitions, and measurements of the subject of inquiry).
(2) Hypotheses (theoretical, hypothetical explanations of observations and measurements of the subject).
(3) Predictions (reasoning including logical deduction from the hypothesis or theory).
(4) Experiments (tests of all of the above)...
A linearized, pragmatic scheme of the four points above is sometimes offered as a guideline for proceeding:
(1) Define a question.
(2) Gather information and resources (observe).
(3) Form an explanatory hypothesis.
(4) Test the hypothesis by performing an experiment and collecting data in a reproducible manner.
(5) Analyze the data.
(6) Interpret the data and draw conclusions that serve as a starting point for new hypothesis.
(7) Publish results.
(8) Retest (frequently done by other scientists).
The iterative cycle inherent in this step-by-step method goes from point 3 to 6 back to 3 again." [Scientific method. Wikipedia]

"Central America ... is the central geographic region of the Americas. It is the southernmost, isthmian portion of the North American continent, which connects with South America on the southeast. When considered part of the unified continental model, it is considered a subcontinent. Central America consists of seven countries: Belize, Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua, and Panama. Central America is part of the Mesoamerican biodiversity hotspot, which extends from northern Guatemala through central Panama. It is bordered by Mexico to the north, the Caribbean Sea to the east, the North Pacific Ocean to the west, and Colombia to the south-east, which is also the most southern point of North America."

"This is a schematic flow diagram of a typical facility for separating and recovering liquid condensate from raw natural gas."

"Natural-gas condensate is a low-density mixture of hydrocarbon liquids that are present as gaseous components in the raw natural gas produced from many natural gas fields. It condenses out of the raw gas if the temperature is reduced to below the hydrocarbon dew point temperature of the raw gas.
The natural gas condensate is also referred to as simply condensate, or gas condensate, or sometimes natural gasoline because it contains hydrocarbons within the gasoline boiling range. Raw natural gas may come from any one of three types of gas wells:
(1) Crude oil wells - Raw natural gas that comes from crude oil wells is called associated gas. This gas can exist separate from the crude oil in the underground formation, or dissolved in the crude oil.
(2) Dry gas wells - These wells typically produce only raw natural gas that does not contain any hydrocarbon liquids. Such gas is called non-associated gas.
(3) Condensate wells - These wells produce raw natural gas along with natural gas liquid. Such gas is also non-associated gas and often referred to as wet gas." [Natural-gas condensate. Wikipedia]
