摘要
本文利用自制的电热温控杯对蒸馏水的比热容进行测定,线性拟合的比热容值与文献值相关度达0.9809。在此基础上分别对固相、液相海波的比热容进行了测定,并且测定了相变过程中海波的相变潜热。实验结果表明,采用笔者的测定的方法,大大简化了测定海波比热容的实验过程,提高了实验的精度。
In this paper, the specific heat capacity of distilled water was determined by the self made electric thermo control cup, and the relative heat capacity of the linear fitting was 0.9723. Under this condition the specific heat capacity of the solid phase and the liquid phase hyposulfite were measured, and the phase change latent heat of the hypo in the phase transition was measured. The experimental results show that the method of measuring hyposulfite specific heat capacity is greatly simplified and the accuracy of the experiment is improved.
