Investigate the physics of instant noodles in a hot cup using Arduino temperature sensors

The study explores the physics of cooking instant noodles in a hot cup using low-cost Arduino sensors developed as a thermocouple and an infrared thermometer. By pouring room temperature water onto a bag of calcium oxide (CaO) contained in the outside cup of the noodles, the exothermic reaction of CaO generates. Its energy is released into the water of the outside cup. This cooks the noodles, which are put into an inside cup. The amount of heat transferred to the water is measured. Moreover, the change in the temperature of the hot cooked noodles with time is investigated using Newton’s law of cooling. The experiment using the Arduino temperature sensors encourages undergraduate students to learn thermodynamics concepts from the instant noodles in a hot cup, primarily found in groceries.
