Given appropriate chemicals and equipment‚ the specific heat capacity and molar mass of a metal‚ enthalpy of neutralization of an acid and base‚ and the enthalpy of solution of an unknown salt can be determined by following specific procedures. All of these procedures require the use of a calorimeter‚ which are of two types: a bomb calorimeter and a coffee cup calorimeter. Calorimeters are simply devices used to measure the amount of heat gained or lost in a system. Although this is not completely
