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.
For the first phenomena, he noted how all combustions involved the formation of fire or light. With that in mind, Lavoisier also observed that this combustion occurs only through dephlogisticated air / pure air. Other airs (e.g. carbon dioxide) act as a fire extinguisher similar to that of water. Another combustion phenomenon he outlined was how the weight of the burnt material directly relates to the amount of air used in the reaction. Moreover, he also described how certain substances turn into acids after it has been burn...
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).

Gasoline is thought to be a helpful substance to all countries worldwide. However, the negative effects are far greater than the positive. A diversity of clean fuels is vital for the political, environmental, and economic health of America. Although gasoline is a product depended on by the United States of America and many other countries, the negative effects are unbearable, dangerous, and unnecessary due to the opportunity to use alternative fuels.
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.
Investigating Factors Affecting the Heat of Combustion of Alcohols PLANNING SECTION Introduction ------------ Alcohols are organic substances, and consist of Hydrogen, Oxygen and Carbon. All alcohols are toxic but the amount that can be tolerated by the human body varies for different alcohols. For example drinking small amounts of Methanol can lead to blindness and even death.
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:
Gasification products can be divided in fuel gases and non-fuel gases. The fuel gas (mixture of Carbon monoxide, Hydrogen and traces of Methane) is called producer gas. In particular, section 2.2 focuses on the non-fuel gases such as Carbon dioxide, Nitrogen, some hydrocarbons and water steam which cannot be utilized for combustion. Table 1 shows that according to the gasifier system and the gasifier agent, the biogas composition
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…
Air pollution is a type of pollution that can severely damage our environment as well as the earth’s atmosphere. Air pollution occurs all the time when the air contains many substances ...
Pollution is so harmful to human beings. Polluted water can cause many kinds of diseases, such as diarrhea, enteritis, and so on. And sometimes the diseases even take man’s life. Dirty air or air-borne garbage causes stinging eyes and running nose. Pollutants are destructive. They will cause runs in stockings and crack rubber tires and they always eat away at stone and rust iron. Time and time again, there are serious accidents that polluted the air. For example, At 1986 there was a bad accident at a nuclear power station in Russia. A cloud of radiation crossed the whole Europe. It is said that 125,000 people died in Russia as a result of illnesses caused by that accident. In 1984 there was an accident at a factory in India and a dangerous cloud gas covered the town of Bhopal. Over 2,500 people were killed that night, and hundreds and thousands of people were injured. Many of the injured lost their sight, and it really dangerous, even in our imagination.
Air Pollution is when a poisonous or a harmful substance is released in the air. There are many form of pollution but air is one of them, it only occurs when dust, harmful gases or smoke enters into the atmosphere and makes it hard for species like plants, animals and humans to live in a difficult situation because of the dirty air.Air Pollution is classified in two sections, invisible air pollution and visible air pollution.. Hence any substance that makes it difficult for the living things that need the atmosphere is air pollution.Humans have been undergoing air pollution ever since the industrial revolution.In order to understand the causes of Air pollution, it is divided into divisions. Primary air pollutants and secondary air pollutants:
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
