The number of molecules arriving at an area on one side of the gas layer, with speed at angle from the normal, in time interval is. These molecules made their last collision at a distance above and below the gas layer, and each will contribute a molecular kinetic energy of where is the specific heat capacity.
2 days ago · October 15, 2024. . Understanding fire science is crucial for investigations. The fire triangle is a traditional geometric model that represents the three components that are required for a fire to start. The fire tetrahedron builds on this model by introducing a fourth important element: the chemical chain reaction.

3 days ago · He had produced oxygen gas by heating mercuric oxide (HgO) and various nitrates in 1771–72. [17] [18] [9] Scheele called the gas "fire air" because it was then the only known agent to support combustion. He wrote an account of this discovery in a manuscript titled Treatise on Air and Fire, which he sent to his publisher in 1775. That document ...
