Ø HOW IS COAL FORMED? Coal is a complex mixture of compounds of carbon‚ hydrogen‚ oxygen along with small amounts of nitrogen and sulphur compounds and some free carbon. Most of our coal was formed about 300 million years ago when much of the earth was covered by steamy swamps. Eventually bacterial and chemical action at high temperature and pressure inside the earth gradually changed the materials to coal. The slow chemical process of the conversion of wood into coal by a biochemical process

Electricity is one of the most important energies in people’s daily life. Without electricity‚ life will be tough and boring. We could only use candles for illumination and firewood for cooking. There would be not PCs‚ no TVs‚ and even no radios. Electricity brings us a great life and it is an affordable energy. The local electricity price in Fairbanks is about 16 cent per Kilowatt-hour. However‚ the waste of electricity is a serious problem in Wickersham hall. When you walking outside the Wickersham

Introduction Scenario 1 There has been a fatal accident- a student has been found drowned in hydro pool. What is the procedure? When a person is drowning‚ the air passages close to prevent water from entering the lungs. This also prevents air from entering the lungs‚ and therefore depriving the victim of oxygen and eventually leading to unconsciousness and death. As in all first aid‚ the key rule is to protect yourself. The student who is drowning can strike out and pull down even the

A balloon-powered car is powered by the air released in the straw. One must blow into the straw which inflates the balloon. When you blow up the balloon‚ set your racer down‚ and let it go‚ escaping air from the balloon rushes out of the straw causing propulsion. The principle at work is Newton’s Third Law of Motion‚ which states that for every action‚ there is an equal and opposite reaction. In the case of the Balloon Powered Car‚ the action is the air rushing from the straw. The reaction is the

the past decade global warming‚ and the potential dangers that goes with it has been a topic‚ which needs to be fixed. Clean coal technologies (CCN) are methods that will lead to mankind taking a huge step in the right direction. First‚ the basic definition of CCT is the process of cleaning coal‚ so when it is used it will not damage the atmosphere. Second‚ after the coal is purified‚ there are two ways of containing the poisons. Finally‚ when CCT is perfected‚ how can leading companies implement

Maria Chriscia Y. Andres 10- SCA Title: The Balloon Powered Car Racer Background of the Study: Sir Isaac Newton developed three laws of motion in 1665 when he was only 23 years old. These laws revolutionized how science explained movement by describing how the forces acting on an object are responsible for the object’s motion. Balloon powered car racer is driven by air coming from a deflating balloon. As an alternative of using electricity‚ these cars make use of the Law of Action and

Hydro One (A) was re-established from former Ontario Hydro who generated electric power and had previously been in business supplying it to several utilities in the Niagara Falls regions in 1998 (Mikes‚ page 1). Hydro one held 5 coal-fried‚ 68 hydro-electronic and 5 unclear power stations‚ and reached power generation and transmission capacity to 30‚000 megawatts. Eventually Hydro one supplied electricity to out side of regions and even other countries (Mikes‚ page 1). In 1906‚ Ontario Hydro was

Wind-Hydro-Thermal Power System A detailed analysis for the power system operation planning is the foremost matter to keep the reserves margin. The reviewed journal paper includes the considerations on wind speed forecast uncertainties‚ system load forecast uncertainties‚ ramp rates of thermal units and spinning reserves. Also‚ instantaneous‚ fast and slow reserve margin at each hour of the planning period is analysed. Thermal plant is the dominator of power generation thus‚ a large-scale hydro system
