| Abstract: | A developed apparatus to measure the specific heat capacity of solids by the mixing method is introduced, which integrates the part of heating with the part of measuring temperature. A device, which can cool the object very fast, is designed, thus the heat loss is reduced. The AD590 temperature sensor being used, the systematic error is further decreased. |
| Keywords: | specific heat capacity principle of thermal equilibrium AD590 temperature sensor |
