When Tora Bora was eventually captured by the U. S. and Afghan troops, no traces of the supposed ' fortress ' were found despite painstaking searches in the surrounding areas.

When this outflow of material eventually impacts the surrounding gas, the shock waves that are created compress and heat the gas.

When the supernova remnant slows to the speed of the random velocities in the surrounding medium, after roughly 30, 000 years, it will merge into the general turbulent flow, contributing its remaining kinetic energy to the turbulence.

When placed together in formation, units can provide an effective defensive front, block an enemy force ’ s escape route, or exploit bad positioning of an enemy force by surrounding it.

When the group scaled a fence surrounding the property, they were seen by Steven Parent, who was leaving in his car.

When the moisture condenses, it releases energy known as latent heat of fusion which allows the rising packet of air to cool less than its surrounding air, continuing the cloud's ascension.

The traditional Chinese response of building higher and higher levees along the banks sometimes also contributed to the severity of the floods: When flood water did break through the levees, it could no longer drain back into the river bed as it would after a normal flood as the river bed was sometimes now higher than the surrounding countryside.

When the Indians proved to be a difficult labor force, peasants from surrounding areas were brought into the region.

When explosive force is applied to concrete, three major fracture regions are usually formed: the initial crater, a crushed aggregate surrounding the crater, and " scabbing " on the surface opposite the crater.

When the charges recombine, the electric discharge ionizes the surrounding air, causing a flash of light.

When referring to the events surrounding unification, however, it carries the cultural connotation of the time and the events in the GDR that brought about this " turnaround " in German history.

When the movie was eventually made, much of the production took place in the hills surrounding Los Angeles.

When this picture is considered in detail, it is seen that the flux tube must charge up and the surrounding plasma must spin around it.

When these are used on fluorescent paper, the inked areas fluoresce less than the surrounding paper area when under an ultraviolet lamp.

When the French Revolution broke out, Nantes chose to be part of it, although the whole surrounding region soon degenerated into an open civil war against the new republic known as the War in the Vendée.

When I had my big job with the double headlights and yards of chrome, the gas people were happy to see me.

When clouds are present, the loss rate of SO < sub > 2 </ sub > is faster than can be explained by gas phase chemistry alone.

When certain ionic compounds containing bromine are mixed with potassium permanganate ( KMnO < sub > 4 </ sub >) and an acidic substance, they will form a pale brown cloud of bromine gas.

When a system, for example, n moles of a gas of volume V at pressure p and temperature T, is created or brought to its present state from absolute zero, energy must be supplied equal to its internal energy U plus pV, where pV is the work done in pushing against the ambient ( atmospheric ) pressure.

When the mask is used in a real scenario, or as part of a drill, there is 9 seconds to put the gas mask on and clear and seal.

When running at lower speeds, quenching is commonly observed in diesel ( compression ignition ) engines that run on natural gas.

When a protostar is formed from the collapse of a giant molecular cloud of gas and dust in the local interstellar medium, the initial composition is homogeneous throughout, consisting of about 70 % hydrogen, 28 % helium and trace amounts of other elements, by mass.

When measuring liquid pressure, a loop filled with gas or a light fluid can isolate the liquids to prevent them from mixing but this can be unnecessary, for example when mercury is used as the manometer fluid to measure differential pressure of a fluid such as water.

When this is true, the two phases will be in equilibrium, and the gas pressure will equal the equilibrium vapor pressure of the liquid ( or solid ).

When the deceleration sensors sense a potential crash, small explosive cartridges are triggered electrically and the resulting pressurized gas feeds into tiny Wankel engines which rotate to take up the slack in the seat belt systems, anchoring the driver and passengers firmly in the seat before a collision.

When stars are born, their birth is accompanied by a strong outward wind of gas and dust.

When enough energy is deposited in a droplet by ionizing radiation the superheated droplet undergoes a phase transition and becomes a gas bubble.

When UF < sub > 6 </ sub > is exposed to water vapor in the air, it reacts with the moisture to produce UO < sub > 2 </ sub > F < sub > 2 </ sub > ( uranyl fluoride ), a solid, and HF ( hydrogen fluoride ), a gas, both of which are highly soluble and toxic.

When the shaped charge detonates, most of its energy is focused on the steel plate, driving it forward and pushing the test gas ahead of it.

When close to a planet with a strong magnetosphere such as Earth or a gas giant, the magnetic sail could generate more thrust by interacting with the magnetosphere instead of the solar wind, and may therefore be more efficient.

When used for etching, ferric chloride does not produce a corrosive gas, as acids do, thus eliminating another danger of traditional etching.

When the working fluid is a gas that is compressed and expanded but doesn't change phase, the refrigeration cycle is called a gas cycle.

When the activation energy is given in molecular units instead of molar units, e. g., joules per molecule instead of joules per mole, the Boltzmann constant is used instead of the gas constant.

When a crash occurs the bladder inflates with a gas to increase the area of the restraint contacting the occupant and also shortening the length of the restraint to tighten the belt around the occupant, improving the protection.

When a binary system contains a compact object such as a white dwarf, neutron star or black hole, gas from the other ( donor ) star can accrete onto the compact object.
