Three Weeks on a Deserted Island

For how many years has man asked the question, “what three items would you bring with you if you were stranded on a deserted island?” Well today that question will be answered. In the following essay it will be proven that an axe, a deep metal skillet, and very large spool of thick rope, would be the three items, which would help someone best survive for three weeks on a deserted island. This will be proven through careful analysis of…

Macromolecules Lab Bio 1 Lab

The macromolecule lab taught us how to set up a comparison to determine what a positive and negative test for a macromolecule looked like. Afterwards we used our positively tested samples as comparisons to determine whether or not the unknown food items that were brought in were positive for any of the four macromolecules. Statement: In this lab we conducted an experiment in order to determine what macromolecules where present in foods and how to distinguish between a positive test…

Boiling Point of Water with Salt Added

Over time, numerous applications for the addition of salt in water have been established and the process of adding salt in water has become a regular exercise wherever water has to be boiled around the world (Bradley, 2006). Purpose The purpose of this project is to study the implications of the addition of salt in the reaction of water to heat. Theory & Hypothesis Upon the addition of common salt (NaCl) in distilled water, it causes the boiling point of…

fairchild Water Technologies, Inc.

I. INTRODUCTION Fairchild Water Technologies was founded in 1980 by Eugene Fairchild. The company’s first product was a desalinator used by mobile home parks in Florida to remove salt from well water supplied to residents. As the desalinator became a huge success, the company expanded into the coastal region’s adjacent to the company’s headquarters in Tampa, Florida, and then to desert areas in the southwestern United States. By 2002, they had expanded their product lines to include desalinators, particle filters,…

does Adding Salt to Water Make It Boil at a Higher Temperature_

Project Design Plan Everyone knows that water boils at 212°F, but does adding salt to a pot of water make it boil at a higher temperature? Being a person that cooks frequently at home, I wanted to test the debated idea that adding salt to my water will make it boil faster. One of my friends says it does raise the temperature and therefore cooks it faster. My other friend says it only helps it taste better. Literature Review Table…

Water Short

‘Water’ is one of the natures precious gifts to mankind. All living things consist mostly of water eg. the human body is of two thirds of water. It is clear, colourless liquid that appears blue when viewed through a thickness of 20 ft. The colour reflects not only from physical causes but also from suspended impurities. The freezing point of water is 0degree centigrade and its boiling point is 100 degree centigrade. Water is the most essential component of life…

Physics Isa Thermistor Generalised Paper 1 Guide

1. My hypothesis is that the resistance decreases as the temperature increases. I predict my results will have a negative correlation, and that as the temperature 2. http://www.gcsesciencemethods.co.uk/2014/05/thermistor-resistance-dependent-on.html http://www.nuffieldfoundation.org/practical-physics/effect-temperature-thermistor The first method contained a risk assessment as well as a choice of two methods, one with a digital multimeter as well as one with a power supply and an ammeter. The second method has an explanation as to how a thermistor works, but I chose the first method because it…
