EXECUTIVE SUMMARY: The study on the calculating cooling time of brewed coffee using differential equation. This was conducted at the University of Rizal System Morong during the first semester of school year 2015-2016. The experiment was conducted in the different coffee shops in Morong, Rizal namely; Infini Tea, Aljen's Coffee Break Lounge, Scholar's Café, Bean in Love. The researchers used the Newton's formula for Cooling and Heating to test if the computed temperature would be equal to the actual data gathered. After using the said formula the researchers concluded that the time rate of change of the temperature of the coffee is proportional to the difference between the coffee and its surrounding medium. The lower the surroundings temperature the shorter time the coffee decreases its temperature and the higher surrounding temperature the longer time the coffee decreases its temperature. The researchers recommend that further studies may be conducted using Cooling and Heating in Differential Equation in other situations.
