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).
The Sci Guys: Science at Home - - Charles's Law of Ideal Gases. Welcome to the tenth episode of season 2 of The Sci Guys. In this episode we will be using balloons to explore one of the gas laws, named Charles's law of id. Find this Pin and more on Best Teacher Tips and Resources.
