I did a research paper in the field of chemistry. I measured the time course of the temperature in reactions of reactive metals with water. As the temperature measurement with mercury thermometer is inaccurate and slow, I used the electronic temperature sensors. I have connected to the Arduino microprocessor, which I have programmed so that the temperature data were sent to a personal computer, and then stored in the file. I processed the data stored in Excel and drew graphs, from which I found the reaction rate and temperature difference of water before and after the reaction. On this basis, I classified metals according to their properties. I came to the conclusion that my computer has greatly eased reading, writing, and editing data, and I assume that it will come in handy in the future as well.
