The increase in the development of the technology and the human race, people failed to take care about the surrounding in which they live in. Thus, most people polluted the environment and thereby reducing the quality of the place which can be harmful to them. Even though, there are several aspects of pollution such as soil, air and water pollution can be detect visually and by tasted. For air pollution that cause by certain gas, it cannot be detect as it odorless, tasteless and colorless. Some of gases are useful in our daily life. It makes our daily life become easier and save time.
Liquefied Petroleum Gas (LPG) is one of the common alternative fuels used in world today. It is a mainstay for heating and cooking in Malaysia. LPG gas is a fossil fuel, like oil and natural gas. It can be refined from oil and natural gas the same way gasoline is refined from crude oil (Grabianowski, 2005). There are two main types of LPG are butane and propane. They are only used in their pure form for test purposes, and are supplied as commercial butane or commercial propane, which are mixtures of the gas with other gases added to improve the working characteristics (Treloar, 2010). The advantages of LPG gas are most of propane comes from domestic sources, less expensive than gasoline and potentially lower toxic, carbon dioxide (CO2), carbon monoxide (CO), and non methane hydrocarbon (NMHC) emissions.
Combustion gas involves a chemical reaction. It will produce heats as the gas reaction changes into a new compound. A compound is a substance with more than one kind of atom (Senese 2010). Combustion byproducts enter buildings and homes directly from the use of unvented kerosene and gas space heaters, gas fireplaces, gas stoves, indoor use of ch...

... acts similarly to a microcontroller unit. It is an open-source electronic prototype platform based on flexible, easy-to-use hardware and software with high performance and special features. Further explanation on this unit will discuss in chapter 2 and 3. For the sensing circuit system, there is MQ-2 which uses to detect two type of gas which is Liquefied Petroleum Gas (LPG) and combustion gas. The outputs of the system are, LEDs and exhaust fan. Global System for Mobile technology (GSM) will use as communication system to sent alert to the authorized person.
For software programming, it will categorize into two which is:
i. Adruino programming ii. GSM programming
Arduino software is used to write the programming for the Arduino board microcontroller. While, GSM programming will use certain library in order to allow the system sent the alert to mobile phone.
Combustion is an exothermic reaction that reacts when in contact with oxygen producing heat and a new product. These reactions are as exothermic as it gets. The general form of a combustion reaction is the reaction between a hydrocarbon and oxygen to create carbon dioxide and water. Hydrocarbon + O₂→CO₂+H₂O. Occasionally, these reactions can release light and produce a flame. To start a reaction, most require a flame to provide heat and initiate the reaction. Combustion is a very common reaction. It's what makes our cars go, and it's what burning is. It is containing carbon which reacts with oxygen to form CO2 and H2O. A simple example of the combustion of Methane, a natural gas, CH4 + 2O2 →CO2 + 2H2O. Another example includes the burning of naphthalene with the equation C10H8 + 12 O2 → 10 CO2 + 4 H2O. The combustion of ethane is 2C2H6 + 7O2 → 4CO2 + 6H2O which is another example. A real life example is the combustion of gunpowder. Gunpowder is a mix of potassium nitrate, charcoal, and sulfur. The potassium nitrate decomposes at a high temperature to provide the oxygen needed. The charcoal and sulfur are the fuels in this reaction. The equation for this reaction is as follows 2 KNO₃ + S +3 C →K₂S + N₂ + 3 CO₂. An incomplete reaction occurs when the oxygen is
Combustion is a rapid, continuous reaction that usually takes place in the gas phase. Wood is an organic compound primarily comprised of cellulose. For wood, the phase change from a solid to gas is almost instantaneous as combustion occurs (Coleman, et al. 95). Ignition occurs when an outside source is no longer needed to sustain combustion (Coleman, et al. 87).
The first thing in a firework is the oxidizing agent. These produce the Oxygen to burn the mixture. Oxidizers are usually nitrates, chlorates or perchlorates. The common oxidizers are nitrates. These are made up of a metal ion and the nitrate ion. I'll use potassium nitrate as an example. Nitrates only give up 1/3 of their oxygen. The resulting equation would look something like this:
oxygen, and cannot be smothered. If you start a chemical fire indoors, it can be

Propane can also reduce emissions. There are two types of propane vehicles on the road today, dedicated and bi- fuel. Dedicated is that the vehicles runs solely on propane. Bi-fuel is that the car can run on propane or gasoline. Bi-fuel is a good idea because if the car runs out of propane it can still run on gasoline. The driver does not have to worry about not finding a propane station with a bi-fuel propane vehicle. According to sumanauto.com propane vehicles are very safe. Just like in gasoline vehicles, propane vehicles have shut off valves and the propane tanks are well made. Propane is a safe and green alternative to gasoline powered
Pollution is affecting many individuals and life, as we know it. We need to do something about how it’s affecting our world. That’s why I urge the issue that more people should realize that pollution is an issue that needs to be prevented because of its negative consequences. Which are health affects, the total destruction of environments, and the death of animals and plants. More awareness must be brought up amongst the people and they must realize the long-term benefits it has for the world.
Full combustion should generate two products only: carbon dioxide and water vapour. Hypothesis Within a molecule there are bond energies that hold the atoms together. When the fuel combusts, a chemical reaction takes place, this breaks the bonds, this requires energy, and makes new bonds, this gives out energy. The energy differences between the two tell us how much energy was given out or taken in. We can show this in a graph.
When these materials burn, they give off hazardous and toxic chemicals, including carbon monoxides (CO), hydrogen sulfides (H2S), and hydrogen cyanides (HCN). The smoke from these materials puts first responders who are not wearing a self-contained breathing apparatus (SCBA) at risk for long-term health illness from chronic conditions or cumulative exposures or immediate death. The public also is at risk, making smoke inhalation the leading cause of death during structure fires (McCreedie, J.,
A combustion chamber is a specific part of an engine where fuel is burned. The combustion engine changes heat energy into kinetic energy. There are two types of combustion engines, one which is internal and the other is external.
Until 10 years ago, air pollution was thought to be just an urban or local problem until it was discovered that the pollutants could move across continents and oceans. Air pollution is the fundamental factor that causes greenhouse gases, hence climate change and global warming. Air pollutants are the waste products generated from industrial and other processes. They usually come in gases, though aerosols (particles suspended in air, emitted as or formed by transformatio...
Air pollution according to the Wikipedia << is the introduction of particulates, biological materials, or other harmful materials into the Earth’s atmosphere, possibly causing disease, death to humans, damage to other living organisms such as food crops, or the natural or built environment>>. Therefore, human being should be aware of the facts that the environment and all living creatures are dying. They need to understand the importance of natural items, the nature, etc…
Every other day a new industries are being set up, new vehicles on roads and trees are being cut to make way for new homes. All of them, indirect way lead to increase in CO2 leads to melting of polar ice caps which increase the sea level and pose danger for the people living near coastal areas. Pollution can have an impact in our health not only affects people with impaired respiratory system such as asthmatics, but very healthy adults and children too. Exposure to pollution for 6 to 7 hours, even at relatively low concentrations, reduces lung function and induces respiratory inflammation and, healthy people during periods of moderate

Pollution is a massive problem that the earth faces. Pollution is the action or process of making land, water, air, etc…, dirty and not safe or suitable to use. Pollution of air, water, and soil are the most complex issues. Various types of gases and toxins that are released by industries
