Introduction
Heat is the form of energy, thermal energy, which flows between two substances due to their difference in temperature.1 The measurement of heat flow is called Calorimetry and the apparatus used to measure the heat flow (temperature change) for a reacting system is called a calorimeter. The calorimeter is well-insulated device that help to minimize the heat exchange between the system being observed and its surroundings.

In this experiment, simple calorimeter, coffer cup calorimeter containing Styrofoam cups is used. Calorimeter contains a thermometer and a stirrer.3 Thermometer is typically inserted in the calorimeter to measure the change in the temperature that results from the reaction. Stirrer is used to keep the contents

Specific heat is the amount of heat needed to raise the temperature of one gram of a substance by 1 C (or 1 K).1 Specific heat of water is equal to 4.18 J/ g℃.1 In order to determine the specific heat capacity of metal, it is necessary to know mass and change in temperature, specific heat of water, also change in temperature and mass of metal used:

q_(H_2 O)=〖S.H.〗_(H_2 O) × m_(H_2 O) × ∆t_(H_2 O)= -〖S.H.〗_M × m_M ×
