A simple calorimeter can be made from two Styrofoam coffee cups, with one inside the Use Over the last 540 million years, icecaps covered at least one of the Earths poles during three b. For example, the unknown metal may not have set in the water bath long enough to reach the same temperature as the water causing inaccurate results when reading temperature. Different states of matter have different amounts of space. This experiment was significant in understanding how heat can be absorbed or released and how using a calorimeter can help measure heat flow. The particles have space between them. mol). We found the mass of the water by subtracting the mass of the empty calorimeter which was 49.987g and the mass of the calorimeter with water which was 87.332g and got the mass of just the water 37.345g. Specific Heat Capacity Laboratory Report. In this experiment, the specific heat and the density of an unknown metal was determined in order to identify the unknown metal. The relationship between the heat added, the mass of a substance, and the temperature change it undergoes is known as the specific heat.
