how much psi is in a can of compressed air
Gas duster True "air dusters" using ordinary air are also available in the market. These typically have much shorter run times than a chemical duster, but are readily refillable. Both hand pump and electric compressor models have been marketed. The maximum pressure for an aerosol can is typically 10 bar (145 psi) at 20 C (68 F).[6] Therefore, a fully compressed air duster will exhaust air about 10 times the can volume. Recently electronic versions which only use air have become viable alternatives that are preferred by many large corporations due to the fact that they contain no hazardous chemicals, are safe for the environment, do not freeze and they cannot be abused by addicts looking to get high. The leading plug-in alternatives are made by DataVac and Airrow and the leading cordless alternative is made by Canless Air System.
Partial pressure The form of the equilibrium constant shows that the concentration of a solute gas in a solution is directly proportional to the partial pressure of that gas above the solution. This statement is known as Henry's law and the equilibrium constant   k  {\displaystyle k}  is quite often referred to as the Henry's law constant.[8][9][10]
Sonic boom When an aircraft passes through the air it creates a series of pressure waves in front of the aircraft and behind it, similar to the bow and stern waves created by a boat. These waves travel at the speed of sound and, as the speed of the object increases, the waves are forced together, or compressed, because they cannot get out of each other's way quickly enough. Eventually they merge into a single shock wave, which travels at the speed of sound, a critical speed known as Mach 1, and is approximately 1,235 km/h (767 mph) at sea level and 20 °C (68 °F).
Popcorn Popcorn, or pop corn, is a variety of corn kernel, which forcefully expands and puffs up when heated.
