In chemistry, the burn rate (or burning rate) is a measure of the linear combustion rate of a compound or substance such as a candle or a solid propellant. It is measured in length over time, such as millimeters per second or inches per second. Among the variables affecting burn rate are pressure and temperature. Burn rate is an important parameter especially in the area of propellants because it determines the rate at which exhaust gases are generated from the burni… Webb6 apr. 2024 · A combustion reaction is a reaction in which a substance reacts with oxygen gas, releasing energy in the form of light and heat.
