TU Braunschweig (German: Technische Universität Braunschweig) is the oldest Technische Universität
(comparable to an institute of technology in the American system) in Germany. It was founded in 1745 as Collegium Carolinum. It is a member of TU9, an incorporated society of the most renowned German institutes of technology. It is commonly ranked among the top engineering universities in Germany.
A combustible material is a material that can burn (i.e., sustain a flame) in air under certain conditions. A material is flammable if it ignites easily at ambient temperatures. In other words, a combustible material ignites with some effort and a flammable material catches fire immediately on exposure to flame.
The degree of flammability in air depends largely upon the volatility of the material – this is related to its composition-specific vapor pressure, which is temperature dependent. The quantity of vapor produced can be enhanced by increasing the surface area of the material forming a mist or dust. Take wood as an example. Finely divided wood dust can undergo explosive flames and produce a blast wave. A piece of paper (made from pulp) catches on fire quite easily. A heavy oak desk is much harder to ignite, even though the wood fibre is the same in all three materials.
