Based off of the calculations, the obscure metal number one is zinc. We measured out 50.0mL of chilled deionized water into a graduated cylinder. These differences, however, it can be accounted for by experimental error; more over there are uncertainty on purity of the. The change in heat can tell us if the reaction is either exothermic - it released or heat into surroundings, or endothermic - it absorbed heat from surroundings. When dealing with the transferring of heat and various process related to heat, the terms convection, conduction and radiation are frequently discussed thoroughly. Specific Heat Capacity Lab Report.

From there, determine which iron compounds are in the stock room bottles based off of the experimental mass percent results., 2. The specific heat capacity of the two unknown metals were determined by measuring the transfer of heat from the metal to water, through the use of a calorimeter. The reason is because it takes more energy to increase the kinetic energy of hydrogen-bonded water molecules than it does for substances in which the dominant intermolecular interaction is the much weaker van der Waals force. 1065 Words.

We began by choosing a sample of metal, finding its mass, and describing it. These experiments lead to reliable results, which in turn determined that the unknown metal was. We heated the 300ml of water to a boil, then placed the metal that was in a tube and waited 10 minutes before we took it out. We subtracted them two and we got the mass of water was 49.176g. This lab is performed in order to determine the total energy in a reaction between zinc and hydrochloric acid. The measure of heat capacity, or the quantity of heat needed to raise the temperature of one gram of a substance by one degree Celsius, is termed specific heat and is represented by the symbol s, Cp, c. The SI units for specific heat are given in J/gC. This lab includes three burning tests of different foods with different energy contents. While waiting on the water and the metal to achieve the same thermal equilibrium, get a coffee cup and measure its mass.
