CITY‚ PHILIPPINES RECEIVED NOVEMBER 20‚ 2012 INTRODUCTION Heat is a form of energy that can be passed from an object with high temperature to an object with low temperature. The heat required to change the temperature of a substance by 1 K is called heat capacity. A calorimeter is a device commonly used to measure the amount of heat that may be produced or assimilated by the system. This device encloses a reaction inside an insulated wall to prevent the exchange of heat between the
