MADALANG, Kyle Marron A. kyle.madalang@yahoo.com E302: Heat and Calorimetry
METHODOLOGY
The experiment was conducted following a two part procedure as follows. In the first part, the procedure aims to determine the specific heat of metals, specifically, the brass and aluminum, both undergone the following procedure, irrespective of their kind to which shall be used first. First, the mass of the metal (), the inner calorimeter () and the water () in the calorimeter in grams was determined through the digital weighing scale. The mass of the water () was obtained by subtracting the mass of the inner calorimeter from the mass of the inner calorimeter with water.
Figure 1: The mass of the inner calorimeter was measured through the digital weighing scale.
Figure 2: To get (), determine the mass of the calorimeter with water and subtract ().
Next, the metal was immersed in the boiling water, allowing an ample time for it to absorb heat from the boiling water. (Note: if the calorimeter was placed quite closer to the electric stove while boiling the water, it is advised to create an improvised wall between the stove and calorimeter to prevent the transfer of heat from the stove to the calorimeter by radiation). Then, the metal was removed from the water, wiping it off to get rid of the remaining moist from the metal’s surface. Determine right away the initial temperature () of the metal. m Figure 3: an improvised wall separating the stove from the calorimeter.
After that, the initial temperature of the water () in the calorimeter was determined using another thermometer. Then the hot metal in the water was put inside and the final temperature of the mixture () was recorded, making sure that only a small amount of heat might transfer out of the calorimeter.
Next, solving for the specific heat of the metal (), an equation was derived using the Law of Heat exchange from (eq.1) and the heat content of (eq.2).
