As a general guide for Zone 2, unwanted substances should only be present under 10 hours per year or 0–0.1% of the time. [3] Unclassified locations Also known as non-hazardous or ordinary locations, these locations are determined to be neither Class I, Division 1 or Division 2; Zone 0, Zone 1 or Zone 2; or any combination thereof.
Operating temperature. An operating temperature is the allowable temperature range of the local ambient environment at which an electrical or mechanical device operates. The device will operate effectively within a specified temperature range which varies based on the device function and application context, and ranges from the minimum ...
Wedge base. W2.1x9.5d base, a common 5-watt bulb in landscape lighting and some interior automotive applications such as the dome light. A wedge base is a type of electrical connector used as a fitting for small light bulbs. It is similar to the bi-pin connector, except that the two "pins" are the same wires that extend into the bulb (rather ...
A temperature coefficient describes the relative change of a physical property that is associated with a given change in temperature. For a property R that changes when the temperature changes by dT, the temperature coefficient α is defined by the following equation: Here α has the dimension of an inverse temperature and can be expressed e.g ...

The 091 manual transmission was a four-speed unit, featuring a lightweight aluminum alloy case; from 1983 a 5-speed transmission was available as an option on certain models; a 5-speed was fitted as standard on Syncro four-wheel-drive models. The automatic features a 1.0 ratio top gear, while the manual features a 0.85 top gear.
Triiodothyronine, also known as T3, is a thyroid hormone. It affects almost every physiological process in the body, including growth and development, metabolism, body temperature, and heart rate. [ 1]
The third law of thermodynamics states that the entropy of a system at absolute zero is a well-defined constant. This is because a system at zero temperature exists in its ground state, so that its entropy is determined only by the degeneracy of the ground state. In 1912 Nernst stated the law thus: "It is impossible for any procedure to lead to ...
