The oxidation of material in rapid, exothermic processes produces the phenomenon known as fire. The process is characterized by various chemical reactions, releasing heat, light, and other reaction products. Listed below are the common characteristics of fire. Learn more about the different types of fire. To understand fire better, learn about the different types of fire, including a review of the basic science of flames. The process also includes the combustion of methane.
Colors of flames
Firelight often resembles flames in color, but how do they get their colors? Flames are made up of atoms of different colors, and their energy levels are determined by the temperature of the material they burn. The colors of flames may also indicate the type of burning. Flames produced by alcohol are pale blue, which indicates the substance has high flammability. This chemical has a very short burning time, so it can ignite very quickly.
Combustion of methane
The oxidation rate of methane has been measured for different temperatures, including 300, 450, and 850 deg C. The maximum rate of methane oxidation is found to be dependent on the first power of temperature and pressure, and the initial pressure. Moreover, it is difficult to measure the time to ignition because the pressure-time curves for the different temperatures are not linear. This makes the conclusions of the studies about the oxidation rate of methane difficult to make.
Convection
During a campfire, heat is transmitted through the three modes of conduction, radiation, and radiation-convection. The first two are easily ignored when people are sitting several feet away. The third, radiation, transfers heat upward from the fire to nearby objects. It is important to know the difference between the three modes because they can affect you differently depending on how close you are to the fire. Radiation transfers heat from the burning log to the unburned wood within the log.
Heat
A fire starts when a substance with enough heat is exposed to an oxygen-rich environment, resulting in a release of energy. The heat caused by the combustion process causes the atoms in the fuel to vibrate, releasing energy in the form of a heat-producing electromagnetic wave. The heat released by a fire is felt and absorbed by thermoreceptors in the body. The flames, which result from this chemical reaction, release this heat energy in the form of light.
Oxygen
The chemical reaction of oxygen with combustible matter causes fire. Oxygen is highly reactive and makes things burn. The two substances make up around 21% of the atmosphere. Oxygen can be obtained in plenty, but it can be hazardous around naked flames. The process of combustion also releases heat and light. Therefore, oxygen is often removed from fire scenes. Those who smoke while using oxygen tanks should understand the risks.
Fuel
Unlike many pre-made smoothies on the market, Fuel for Fire is a nutritious source of fuel. It contains high-quality protein and natural fruit purees for the optimal blend of energy. This smoothie is also gluten-free and convenient to take on the go. It is a great choice for breakfast or post-workout recovery and will keep you fueled throughout the day. You’ll be surprised at how healthy it is, too!
