Drew Staples 6/12/14 Properties of water Question Does mixing water with other substances change it’s boiling point. Research The boiling point of a liquid is when the temperature causes the vapor pressure to be equal to the air. Air density will change waters boiling point. High altitudes give water a lower boiling point. Hypothesis If the water is less dense then it will boil faster and the boiling point will be lower. Materials 1 Pot A Sink A Stove 1 tablespoon of sugar 1

Reuse‚ Revival‚ and Recarving: Ancient Granite Columns in Renaissance Rome Michael J. Waters Worcester College‚ University of Oxford michael.waters1@gmail.com Architects of the Italian Renaissance often quoted ancient architectural details in modern designs as an act of reference and revival. While historians frequently note this common method of transumption‚ the creation of all’antica architecture through the use of ancient building materials has gone largely ignored. This paper argues that the

Why has access to water been such an important? There is a lot of reason why‚ I will give you a few. Water was needed to feed the people farm life‚ water was important to keep one alive‚ and the most important‚ is water is used to grow plants and other material. How did ancient societies address the problems associated with harnessing these powerful resources? There were a lot of different ways to address the problems. Some use rules‚ maps‚ there were disputes‚ fights‚ and agreements were made

The hypothesis was stated to be supportive based on the difference in all three slides. In the first method‚ a drop of sheep blood was placed on the slide and was covered with a coverslip. Second slide‚ the blood was placed on a slide then a solution of 0.9% NaCl was added. The cover slip was placed

project is to determine whether river water or lake water is cleanest as it relates to tap water. The independent variables being tested in this experiment are the different waters being tested which are river water‚ lake water‚ and tap water‚ which is the control. The dependant variable is which of the three waters are the cleanest as it relates to unfiltered tap water. The purpose of this experiment is to determine what the different aspects of the three types of waters are and how that relates to cleanliness

Purification of Water Domestic: Distillation - In the process of distillation water is heated and evaporation takes place‚ whereby water changes back to water when cooled; this process is called condensation. The condensed water is the purest form of water‚ free from microbes‚ and impurities. Boiling - Boiling is the best and simplest method to purify water. After straining the water twice through clean muslin cloth‚ it is boiled for ten minutes lo kill the microbes present in it and also remove
