The economics term cost, also known as economic cost or opportunity cost, refers to the potential gain that is lost by foregoing one opportunity in order to take advantage of another. The lost potential gain is the cost of the opportunity that is accepted. Sometimes this cost is explicit: for example, if a firm pays $100 for a machine, its cost ...
v. t. e. Economics ( / ˌɛkəˈnɒmɪks, ˌiːkə -/) [1] [2] is a social science that studies the production, distribution, and consumption of goods and services. [3] [4] Economics focuses on the behaviour and interactions of economic agents and how economies work.
The TCRE can be calculated based on a formula for the ratio of temperature change to cumulative carbon emissions (measured as CO 2 ), which is the net carbon remaining in the atmosphere after accounting for relevant sources and sinks. [6] As a measure of atmospheric carbon change, the TCRE parameterizes how sensitive the climate is to carbon ...

In electrical and safety engineering, hazardous locations (HazLoc, pronounced haz·lōk) are places where fire or explosion hazards may exist. Sources of such hazards include gases, vapors, dust, fibers, and flyings, which are combustible or flammable. Electrical equipment installed in such locations can provide an ignition source, due to ...
Thermodynamic temperature is a quantity defined in thermodynamics as distinct from kinetic theory or statistical mechanics.. Historically, thermodynamic temperature was defined by Lord Kelvin in terms of a macroscopic relation between thermodynamic work and heat transfer as defined in thermodynamics, but the kelvin was redefined by international agreement in 2019 in terms of phenomena that are ...
v. t. e. An economic model is a theoretical construct representing economic processes by a set of variables and a set of logical and/or quantitative relationships between them. The economic model is a simplified, often mathematical, framework designed to illustrate complex processes. Frequently, economic models posit structural parameters. [1]
