Purpose: The purpose of this experiment is to measure the rate of increase (slope) of the water given two different starting points to the boiling point of 212 degree Fahrenheit in the span of time. The rate of increase in water temperature as it is heated given all control variables are the same such as one quart aluminum pot holding three cups of refrigerate and room temperature water. The study is to conduct weather if both types water will have the same slop of increase. Procedure: The first step was to fill a jug full of water and leave it in the fridge to cool down overnight and another jug full of water so that it becomes part of room temperature. Before the experiment, take out the fridge water and measure out three cups and pour it into the one quart pot and measure the water temperature before placing it on the stove. Then turn the stove on to maximum heat as well as the timer. While the water is reaching to the boiling point measure and note the temperature for every minute. Next, let the stove and the pot cool down for few hours. Then take jug with room temperature water and pour out three cups into the pot. Before placing it on the stove and heating the water to repeat the experiment, the water temperature was taken to ensure that it was approximate to the room temperature. Literature Review: According to an article in The New York Times, the notion of a body of cold water will reach boiling point quickly as to an identical body of hot water under the same parameters is false (O'Connor, 2008). In this experiment it is not to prove what has already been done, rather to find if the rise of water bodies would be parallel. The notion is to calculate the slope of increase in water temperature given two different starting points, are they both identical. Furthermore, the article suggests that cold water generally gains heat more rapidly (O'Connor,
