| Abstract: | With the regression analysis of changing numbers of enthalpy in ideal gas with temperature changes, h=h(T) can be obtained. Then derivative is obtained from this equation, so cp=cp(T) can be drawn, which shows the relationship of molecular thermal capacity with temperature changes. Entropy function can then be obtained by integral equation. |
