Reference Paper Have you ever sat there and just wondered about various things dealing with certain things in chemistry known as calorimetry or thermochemistry? No, yes, maybe, whatever your answer, you really thought yes, so I will explain these topics to you in this article and teach you how they work so that you can understand these things if you ever encounter them. a real-world situation.We'll start with calorimetry, going over all the basic things such as what it actually is, how to write a calorimetric equation, and even what a calorimeter is and how to use it. It's time to start calorimetry the best way: with the definition: because you need to know what it is before learning anything else about it. Calorimetry is the quantitative measurement of heat required or released during a chemical process and is just a general term for everything related to this, including finding the heat required for the equations used to understand everything . Now that you know what calorimetry is, we can move on to the calorimeter and how it works. A calorimeter is an instrument for measuring the heat of a reaction during a well-defined process. There are 2 different types of calorimeters, the first being what is called a bomb calorimeter. This is a more advanced calorimeter, it represents a constant volume using the internal energy change between reactants and products. This device is more accurate, but also more expensive, so just in case you need one but don't have one, there is a simpler, cheaper calorimeter consisting of two foam cups, a thermometer, a glass stirrer and a cork stopper. cork. This measures the constant pressure and the change in enthalpy during the reaction. As I said above, the... middle of paper ... combustion of paraffin wax through the use of calorimetry, and I believe this has been respected. It was possible to find the heat of combustion with an error of 7%. This could have been more specific, but we'll discuss that in a moment. The lab's goal was achieved by lighting the candle and observing a change in mass. The heat of combustion was then calculated using this and other laboratory data. So yes, I believe that the laboratory's objective was achieved during the experiment. Now let's talk about errors. The lab was completed and the objective was met, but with an error of 7.14%. This error could have been caused by different things. The candle may have burned too long, or not long enough, there may have been incorrect measurements and more. However, overall I think this lab went well and errors were almost minimized..
