It should be kept in mind that explosives are generally unstable compounds. Once the exothermic decomposition or combination reaction is started, the temperature rises and the reaction accelerates it usually cannot be stopped. 

Physical explosions are those in which no chemical or nuclear reaction occurs. The most frequent example is the rupture of a vessel whose contents, either gas or liquid, exist under high pressure. If the containing vessel bursts, its contents are free to expand and a shock wave is formed. Even a common automobile tire can explode if it is highly overinflated. 

Liquids that have a normal boiling point well below ambient temperatures are sometimes stored (under their own vapor pressure) at pressures well above atmospheric pressure. If the tank holding the liquid bursts, part of the liquid vaporizes extremely rapidly and expands, forming a shock wave. This process is called a boiling liquid expanding vapor explosion (BLEVE) and the resulting explosion can be very destructive. 

Explosions can be used for constructive purposes, such as mining and road building for entertainment, such as fireworks or for destructive purposes, such as military weapons and terrorist bombs. They may be either deliberate or accidental. Explosive materials must always be handled with extreme care to prevent accidents. Such caution must be exercised with not only industrial explosives, but also commonly encountered materials such as fireworks, laboratory and industrial chemicals, and flammable gases, see also Fire, Fuels, Power Plants Fireworks Kinetics Nuclear Fission Nuclear Fusion Thermodynamics. 

Observations are the heart of the scientific method, but human perception is faulty when it comes to observing absolutes. That is, one may be able to say that this liquid is hotter than that liquid, but not by how much, nor

Fahrenheit, Gabriel Daniel (1686-1736) German physicist and engineer but lived most of his life in the Dutch Republic in 1717, he settled in The Hague with the trade of glassblowing, making barometers, altimeters, and thermometers. From 1718 onwards, he lectured in chemistry in Amsterdam.

The formulas for getting back and forth between the Fahrenheit and Celsius temperature scales are °F = 9/5°C + 32 and °C = 5/9(°F — 32). These temperature scales are named for their inventors, Daniel Gabriel Fahrenheit and Anders Celsius. 

Gabriel Fahrenheit in 1714 suggested for the zero point on his scale the lowest temperature then obtainable from a mixture of salts and ice, and for his 100° point he suggested the highest known normal animal temperature. Express these extremes in Celsius.

He turned his interests from steel to temperature, and in 1730 he presented to the Paris Academy his study A Guide for the Production of Thermometers with Comparable Scales. He wanted to improve the reliability of thermometers based on the work of Guillaume Amontons, though he appears not to be familiar with Daniel Gabriel Fahrenheit s earlier work. 

In the United States, temperatures are frequently measured on the temperature scale devised by Gabriel Fahrenheit (1686-1736), a German instrument maker. On this scale the freezing and boiling points of water are defined as 32°F and 212°F, respectively. In scientific work, temperatures are often expressed on the Kelvin (absolute) temperature scale. As we shall see in Section 12-5, the zero point of the Kelvin temperature scale is derived from the observed behavior of all matter. 

Fahrenheit In the United States, the Fahrenheit scale is used to measure temperature. German scientist Gabriel Daniel Fahrenheit devised the scale in 1724. On the Fahrenheit scale, water freezes at 32°F and boils at212°F.
