The specific heat value is obtained from the weight of ethanol and water, their cooling times, and the water equivalent of the experimental tools used in this study. To clarify the reason for mismatch between the experimental and the previously reported specific heat values, we examined the effect that the aforementioned five characteristics had on the specific heat value.

We precisely measured the amount of time needed for the temperature of ethanol and distilled water reach 45 ℃ and 35 ℃ using a stopwatch and found that the obtained specific heat value improved to

内容記述 | We improved the method of measuring specific heat of ethanol based on Newton’s law of cooling in physical experiments by changing how the cooling times of ethanol and distilled water are measured. In our previous experiments on the cooling method, the obtained specific heat value often did not coincide with the previously reported value. The specific heat value is obtained from the weight of ethanol and water, their cooling times, and the water equivalent of the experimental tools used in this study. To clarify the reason for mismatch between the experimental and the previously reported specific heat values, we examined the effect that the aforementioned five characteristics had on the specific heat value. We determined that the weight of the liquid and water equivalents had a relatively small impact, whereas the accuracy in measuring the cooling time had a substantial effect on the value of the specific heat of ethanol. We precisely measured the amount of time needed for the temperature of ethanol and distilled water reach 45 ℃ and 35 ℃ using a stopwatch and found that the obtained specific heat value improved to 0.685 cal / ( g・K ) which is a negligible 5% difference from that previously reported. | |||||
