THE SPECIFIC HEAT OF SOLID Abstract: In this experiment, the specific heat of a metal object will be determined with the help of calorimeter. Equipment: Calorimeter Thermometer Beam Balance Timer Tongs Solid metal objects Water heater with Steam Jacket Introduction: The specific heat capacity of a substance is defined as: The amount of heat required to raise temperature of 1 kg mass of that substance through 1K. Mathematically, it can be represented as: c = ∆Q m ∆T (J/kgK) (1)
Law of conservation of energy will help in calculating the specific heat of the substance. Whenever, there is some change in the temperature of some objects, it means thermal energy is flowing from high temperature to low temperature. The specific heat is the measure of that heat transferred for specific amount of substance and temperature change. So, if system doesn’t lose any heat by any process then the total energy gained by cold body will be equal to total energy lost by the warm body. i.e, ∆Q = 0 (2) m s c s ∆T s + m c c c ∆T c + m w c w ∆T w = 0 (3) Where subscripts s, c and w are for solid, calorimeter and water respectively. m =mass of substance
