Specific Heat of SolidsTo determine the heat capacity of a calorimeter.To determine the specific heat of certain solid specimens.Research InstrumentsThe materials and apparatus used in the Linear Expansion experiment are as followed:expansion apparatus with dial gauge; steam boiler and tripod stand; Bunsen burner; thermometer;two metal pipes of different material;
The materials and apparatus used in the Specific Heat of Solids experiment are asfollowed: calorimeter; 300g or more solid samples; 250ml beaker; thermometer; rags; boiler;digital platform balance;Research DesignThe study utilized the experimental method of research in which it used laboratorymaterials and equipment to answer the objectives of experimentation and the relationship inbetween variables presented.For the Linear expansion experiment, a thermal expansion set-up will be used see figure.Heat will be transferred with the use of steam and changes in the physical property of the solid inquestion will be detected with the more accurate than a ruler, dial gauge. Data is then tabulatedand given equation for determining the coefficient of linear expansion we can solve thiscoefficient and identify the solid.For the specific heat experiment, a calorimeter will be used to identify the specific heatsof different materials. First, we identify the specific heat of the calorimeter itself then we use thedata to identify any solid in the system using equation. Theory
To understand the concept of thermodynamics, one must familiarize with the concepts ofbasic linear expansion and heat capacity. For Linear Expansion:The fact that most objects expand when heated is common knowledge. The change in thelinear dimensions of a solid is very nearly proportional to the temperature change over a considerable range of temperature. The coefficient of linear expansion α of a substance is defined as the fractional change in its length for every one degree change in its temperature, that is,α=∆ LLo(TfTo)Equation (1)where L0is the original length at initial temperature T0and L is the change in length. The coefficient of linear expansion of a material is a measure of its thermal expansion properties.For Specific Heats:Different bodies require different amounts of heat to raise or reduce their temperature by one degree. This amount of heat is called the heat capacity, C, of the body. Heat capacity depends on the mass and nature of the substance the body is made of. The amount of heat
required to raise the temperature of a unit mass of a substance by one degree is called the specific heat capacity, c, or specific heatof the substance. In mathematical form,c=∆Qm ∆TWhere c is the specific heat in Joule/kg*celsius0, ΔQ is the amount of heat in Joules, m is themass of the substance in kg, and ΔT is the change in temperature in C0*USC Physics 31 Lab ManualPart AThe heat capacity Cc of the calorimeter itself is determined by mixing cold and hot water.
