【多选题】
A <{p}>Since the residual function is the difference between the properties of two isothermal states, the residual function cannot be used to calculate the change of properties with temperature<{span style="font-size: 1em;"}>由于剩余函数是两个等温状态的性质之差,故不能用剩余函数来计算性质随着温度的变化<{/span}><{/p}><{p}><{br/}><{/p}>
B <{p}>The basic thermodynamic relation dH=TdS+Vdp applies only to reversible processes<{span style="font-size: 1em;"}>热力学基本关系式dH=TdS+Vdp只适用于可逆过程<{/span}><{/p}><{p}><{br/}><{/p}>
C <{p}>The enthalpy or entropy values obtained from vapor tables or diagrams of a pure substance from different sources are not necessarily the same<{span style="font-size: 1em;"}>用不同来源的某纯物质的蒸气表或图查得的焓值或熵值不一定相同<{/span}><{/p}><{p}><{br/}><{/p}>
D <{p}>Ideal gas thermal tolerance CP-cv =R also applies to ideal gas mixtures<{span style="font-size: 1em;"}>理想气体热容差Cp-Cv=R也适用于理想气体混合物<{/span}><{/p}>
