Proper Use Of Micropipettes A micropipette is one of the instruments that is usually used in science laboratories .Micropipette are used to accurately measure and dispense small volumes of liquid . The capacity of a micropipette can range from less 1µl to 1000µl (1ml) .There are glass pipettes ‚ air displacement pipettes ‚ and positive displacement pipettes . Mostly ‚ the air displacement pipettes and positive displacement pipettes are used . Firstly ‚ the piston is moved to the appropriate

Factors that affect climate Latitude: Ocean Currents: Wind and air masses: Elevation: Relief: Near water: Global Factors that Affect Climate As the suns UV rays hit the earth they hit is directly at the equator causing more heat. Because these rays are direct and they hit direct at one spot. For part a‚ the earth start to slope‚ in which the sun’s rays have to hit a larger areas‚ and have to travel further distances. As the latitude increases‚ the average annual temperatures decreases. In North

Do you ever wonder why a boat floats and a rock doesn’t? Well I do. A Boat floats because of buoyancy and it remains lighter than the amount of water it displaces. Buoyancy is an interesting topic. Buoyancy can happen in any fluid and air. The buoyant force applies not just to water but to any fluid...A fluid is a substance that is able to take the shape of a container in which it is placed.” The source of this information is http://blackbirdlibrary.pbworks.com/w/file/fetch/70171466/dFlaoting

Module 2 Honors Extension: The Physics in Swimming Physics is defined as the branch of science concerning the study of matter and energy and the interactions between the two. Physics tries to explain the nature of the world around us‚ how things happen and why. Swimming displays some physical properties‚ such as buoyancy‚ drag resistance and propulsion. We swimmers are at a constant battle to stay afloat‚ while fighting through the water and propelling ourselves forward‚ and we do so using technique

Heat Transfer Through Jacket Objective The objective of this example is to analyze heat transfer in a pilot plant using simulation models. The first step is to use pilot plant data to calculate heat transfer parameters. The second part involves using simulation models to examine the trade-off between jacket parameters and heating times. Process Description Assumptions: The stirred tank is assumed to be perfectly mixed. The contributions of agitator work‚ heat loss to environment

Crash Course in Density Jonathan Cerreta Chemistry As flight 143‚ a twin engine 767‚ was passing over Red Lake on its was to Edmonton‚ Canada‚ the left front fuel pump warning light went on. There were a few possibilities for this to happen‚ such as the fuel pump failing‚ a fuel line clogging‚ or a empty fuel tank. The former two were easily dealt with‚ since the plane could fly without one fuel pump. However‚ the last possibility was horrifying. After a few minutes‚ the second fuel pump

Compaction is the process of densification of soil by reducing air voids.The degree of compaction of a given soil is measured in terms of its dry density.The dry density is maximum at the optimum water content.A curve is drawn between the water content and the dry density to obtain the maximum dry density and the optimum water content. Dry density = Where : M = total mass of the soil V = volume of soil
