Partner’s name: Samiksha Pathak Aryal Measuring Specific Heat Capacity of Unknown Metal
The purpose of this experiment is to identify the unknown sample by calculating its specific heat capacity.
1. Introduction:
Heat is a form of energy that is transferred between objects with different temperatures. The amount of heat released or gained by an object (q) depends on the mass of the object (m) and the change in temperature of the object (∆T). q = mCs∆T
In this equation, the proportionality constant Cs is called the specific heat capacity and every substance has a characteristic value. In this experiment, we will determine the specific heat capacities of an unknown metal by observing the transfer of heat from a heated piece of metal to a sample of water at room temperature. To calculate q for the metal and the water, we had used above equation, where each variable (m, Cs, and ∆T) corresponds to either the metal or the water. By comparing the experimental specific heat capacity to a table of known values, we were able to identify the metal. …show more content…
