Hold the gas collection tube at an angle as you fill it completely with tap water‚ until it is nearly overflowing. Holding the tube at an angle allows the air bubbles to escape. 6. Place the magnesium in the mouth of the gas collection tube so that it is about three cm below the surface of the water. Fold the thread extension over the side of the

INTRODUCTION: Oil and gas conservation means their better and more efficient use with regard to economic social or environmental costs and benefits resulting in attainment of higher energy use efficienciesm minimixation of wasteful practices. WAYS TO CONSERVE OIL AND GAS IN OUR DAILY LIFE: -The simplest way to conserve oil is to cut down the use of cars and bikes -Walk‚run or use bicycle or electric bike to reach your distination. It not only conserve oil but also

Chapter 3 Fluid Statics: Definitions Statics: ∑F = 0. In statics we have only pressure as surface force and weight as body force. Thus‚ when fluids are still‚ the pressure is balanced by the fluid weight. No relative motion between adjacent fluid layers. Shear stress is zero Only _______ can be acting on fluid surfaces Gravity force acts on the fluid (____ force) Applications: Pressure variation within a reservoir Forces on submerged surfaces Buoyant forces 9/4/2013 1 Pressure Pressure is defined

reason why water has a high/strong surface tension. Heat of Vaporization-the quantity of heat a liquid must absorb for 1 g of it to be converted from the liquid to the gaseous state. Evaporative Cooling- The faster molecules escape and become a gas and the slower/cooler molecules left behind‚ causing a cooling effect. Specific Heat- A measurement of how well a substance resists changing its temp when absorbs or releases heat. Heat-the measure of the total quantity of kinetic energy due to

WORKING PRINCIPLE The aqua silencer is more effective in the reduction of emission gases from the engine exhaust gas using perforated tube. By using perforated tube the back Pressure. Will remain constant and the sound level is reduced. Using the perforated tube the fuel consumption remains same as conventional system. By using water as a medium the sound can be

Oil and Gas PricesOil and Gas 2There are many issues that cause the cost of oil and gas to increase. The main contributing issue to the increasing cost of oil and gas is supply and demand‚ when demand is greater than supply‚ the price of oil and gas will increase. The factors that affect supply include increased demand‚ problems with refineries and pipelines‚ and disruption to supply or threat of disruption to supply.With the increased demand for oil in the United States and other countries such

Research question/Aim Extract copper from copper oxide by reduction using butane gas Hypothesis The butane gas will reduce the copper oxide and leave behind pure copper. This will allow us to find the empirical formula of the copper oxide as well as the masses of oxygen and copper Variables Dependant variable The dependant variable will be the reduction of the copper oxide which will be calculated at different temperatures. Independent variable The independent variable here
