    Surface Tension My problem was to find out how to test or measure surface tension. I think the reason of some of the force in surface tension is cohesion and gravity. Surface Tension is the condition existing at the free surface of a liquid, resembling the properties of an elastic skin under tension. The tension is the result of intermolecular forces exerting an unbalanced inward pull on the individual surface molecules; this is reflected in the considerable curvature at those edges where the liquid

    Beneath the Surface Review I think the key message that the play was trying to convey was that mistakes happen all the time. In this case, the purpose of the main character’s “dig” through Earth was to help him learn how to forgive himself and be able to move on with his life. The opening act of the play started with the main character, Andy, digging his way from Hawaii to Botswana. Over the course of his journey, the audience is introduced to an array of characters that are responsible in helping

    The Study of Si Surface Structures The goal of this study is to determine the ratios of surface type upon the Si sample. Data is collected from the Si samples using SPALEED. By analyzing the data from dates where combined surfaces are present it is possible to determine the amount of certain types of surfaces present on the sample. The ultimate goal is the ability to control the growth of Pb islands upon the Si crystal. Applications of this research include the design of advanced microprocessors

    Chemical Transport During Surface Irrigation Surface irrigation, the most prominent method used for irrigating agricultural crops, is the flowing of water across the field surface. As the water flows, it infiltrates into the soil. The amount of water applied to the field is regulated by the length of time that the water is allowed to flow. Surface irrigation can be subdivided into following four types based the amount of water flow control; wild flooding, graded boarders, level boarders and

    Investigating Surfaces for Insulating Boiling Water in a Flask Aim I'm investigating which surface (matt black or silvery) is best at insulating boiling water. I will investigate this by covering two equally sized conical flasks in different materials; one in matt black and one in silvery. After that I will fill each of the flasks with an equal amount of boiling water. At regular intervals of 1 minute I will measure the drop in water temperature in each flask. Prediction I predict

    The Effect of Weight on Sliding Friction Between a Block and Surface Planning ======== In this investigation we are going to find out what effect weight has on sliding friction. Friction is the force that is between two objects that are in contact with each other. The force is always present even though people only think it is there when the object is moving. Leonardo da Vinci was one of the first people to experiment with the idea of friction. He came up with two types of friction;
