Student Calorimeters play a major role in helping students learn about energy and heat transfer. Basically, they are devices used to measure the amount of heat energy during chemical or physical processes. A student can literally watch the energy being released or absorbed when two substances are mixed, or when a substance changes its state, through a calorimeter experiment. This method of learning by doing makes science interesting, enjoyable and easily comprehensible. HERE AT Maihun, WE BELIEVE LEARNING SHOULD BE FUN AND OUR CALORIMETERS BRING SCIENCE TO LIFE IN A HANDS-ON EXPERIMENTAL MANNER. They are able to carry out experiments using this Experimental Kit, collect information and view the real results; this also helps them understand principles of science better.
When examining the subject of calorimetry, students might face certain problems which lead to poorly performed experiments. Such kind of problem could be for example not sealing the calorimeter properly. If the lid isn't firmly closed, Heat will be able to get out so you wont be able to get accurate results. The explanation behind this is that a calorimeter is a device that isolates heat, so any heat loss will affect the temperature measurements. Another reason was the improper measurement of materials. To give you an example, if the student chooses more or less water than supposed to, that will definitely affect the calculations. Simple Calorimeterneeds very accurate quantities in order to give correct answers. Besides, sometimes students forget about the heat that the calorimeter absorbs. This is called the heat capacity of the calorimeter and, if not included in the calculation, can affect your final results. Finally, a lot of students do not wait long enough for the temperature to stabilize before taking the readings. That can lead to incorrect data.
When choosing a calorimeter for school, you have to consider a few things. It has to be simple first of all. A perfect student calorimeter needs to have easily comprehensible directions and be ready for use. This allows students to focus on their investigations rather than struggling with complicated equipment. Then, you should look for a device that is made sturdy. In addition, since students may not always be careful with it, the students' calorimeter should be able to withstand a few bumps and drops. The design of the structure also helps to ensure that it will last a long time.
Another important point is the accuracy of the instrument. A perfect, top, quality calorimeter should be able to give the accurate value of TL. This is very important as even small mistakes can cause great errors in the experiment. Some calorimeters come with digital displays for easier temperature reading. Also, when purchasing a calorimeter, remember to consider the temperature range. That is to say, it should be equally efficient in working with hot or cold fluids. Plus, if a calorimeter can measure heat capacity, it will surely be a great help to the students in analyzing their results. According to Maihun, School Calorimeter Products should be Educationally, convenient, Student, friendly, and have all those features.
When a students calorimeter is misbehaving, there are some simple methods that one can attempt to get the system working properly again. First, if the temperature readings are out of the blue, the first suspect must be the seal. Make sure you close the lid nicely before you start the experiment. Otherwise, the heat will go out and the readings will not be correct
Moreover, if the seal is still good, the next thing to do is to check how much water you have used. The students may check their measurements again to be sure of their amount. The use of too much or too little water can influence the results.
