Calorimetry refers to the science in which a calorimeter is used to measure the quantity of heat transferred to or from and object Calorimeters are designed to stop heat from being gained or lost due to the surrounding elements The embodiment of a calorimeter is usually copper (Cu) as the burning of the fuel or alcohol is an exothermic reaction and heat can move efficiently through copper. Allowing the calorimeter to reduce the amount of energy required to burn through the alcohol, meaning that enthalpy value is closer to the accepted value.
The accepted value denotes a value of a substance accepted by almost all scientists Enthalpy refers to the amount of heat content used or released in a system at constant pressure The amount of enthalpy that is created during the process of combustion can measured using the formula Q= mc∆T
Q meaning the heat output
M the mass of the product
C the specific heat
∆T the change in temperature (⁰C)
Heat contents= the heat given out when burned/ mass of fuel burned in grams …show more content…
In this case ethanol (C₂H₆O) has an accepted value of 1300 kJ/mol Understandingly, in order for ethanol to beneficially the amount of energy used in combustion must be 1300 kJ/mol. Ergo this equation will produce a value that is close to the accepted value however, due to a large amount of heat escaping through the spatial surroundings of the calorimeter; the accepted value will not be fully achieved unless a professional calorimeter is used. Moreover, in most cases efficient calorimeters cannot be sourced due to their expensive nature. Hence copper calorimeters are constructed in such a way that they will help produce an enthalpy value as close to the accepted value as possible. Although copper calorimeters conduct heat easily, there is a significant amount of heat being lost due to the empty space around the flame, as well as the lack of heat being
