Using the results of thermodynamics only, we can go a long way in determining the expression for the entropy of an ideal gas.

Using more sophisticated microdiffusion techniques, they tested 22 samples from the gas chambers, delousing chambers ( as positive controls ), and living quarters ( as negative controls ), finding cyanide residue in both the delousing chambers and the ruins of the gas chambers but none in the ruins of the living quarters.

Using his observations, Cavendish observed that, when he had determined the amounts of phlogisticated air ( nitrogen ) and dephlogisticated air ( oxygen ), there remained a volume of gas amounting to 1 / 120 of the original volume of common air.

Using this gunpowder, the leaders of the Sonderkommando planned to destroy the gas chambers and crematoria, and launch the uprising.

Using the ideal gas law to replace with nRT / V, and replacing ρ with nM / V, the equation for an ideal gas becomes:

Using the engine bell as a ' gas generator ' also makes it very tolerant of fuel contamination because of the wider fuel flow channels used.

Using the equation of state for an ideal gas,,

Using the coal gas waste as feedstock, researchers developed new processes and synthesized

Using a consumable electrode and a carbon dioxide atmosphere as a shielding gas, it quickly became the most popular metal arc welding process.

** Using Nitrox as a bottom gas

** Using Nitrox as a decompression gas

* Using too much air from scuba diver's breathing gas supply, resulting in an out of air incident.

Using these prices, a heat pump with a COP of 3. 5 in moderate climate would cost $ 0. 97 to provide one therm of heat, while a high efficiency gas furnace with 95 % efficiency would cost $ 1. 22 to provide one therm of heat.

Using a deuterium-tritium gas mixture, self-replenishing D-T targets can be made.

Using a fuel referred to as liquefied natural gas ( LNG ), its first flight was in 1989.

Using inflexible pieces of polyethylene slag given to him by DuPont, Tupper purified the slag and molded it to create lightweight, non-breakable containers, cups, bowls, plates, and even gas masks that were used in World War II.

Using a European crafts system into the late 19th century it was difficult to meet demand for products such as sewing machines and animal powered mechanical harvesters.

Using lead pellets, some current spring powered. 177 pellet guns can break the sound barrier.

Using a powered wingpack, Yves Rossy became the first person to attain the maneuverability of an aircraft, moving only his body for steering ; his experimental wingpack, however, is not commercially viable because the materials required in construction are cost-prohibitive.

Using the Third Rail system, trains powered by electric motor cars ( or carriages ) began running on 17 April 1916 but as Horwich was by then involved in war work, deliveries of the new electric stock were delayed and it was not until August 1916 that steam trains were withdrawn from the route.

Using axes, adzes and draw knives, hand powered auger drill bits ( bit and brace ), and laborious woodworking, artisans or farmers could gradually assemble a building capable of bearing heavy weight without excessive use of interior space given over to vertical support posts.
