Gunpowder's burning rate increases with pressure, so it will burst containers but just burns in the open. Ignition of the powder packed behind a bullet must generate enough pressure to force it from the muzzle at high speed, but not enough to rupture the gun barrel.
The gas constant occurs in the ideal gas law, as follows: where P is the absolute pressure (SI unit pascals), V is the volume of gas (SI unit cubic metres), n is the amount of gas (SI unit moles), m is the mass (SI unit kilograms) contained in V, and T is the thermodynamic temperature (SI unit kelvins).
Steps for Balancing Chemical Equations. Share. Boyle's Law is a special case of the Ideal Gas Law in which the pressure and volume of an ideal gas are inversely proportional to each other, providing the temperature and mass of the gas are held constant. Here's an example of how to perform a calculation using Boyle's Law.
