In steam tables, the values are presented in which of the following terms?

Steam tables present values primarily in specific terms, which refer to the properties of substances per unit mass. Specific terms allow for easier comparison and analysis of thermodynamic properties, such as specific volume, specific enthalpy, and specific entropy, which are crucial in understanding the behavior of steam and water in various phases and conditions.

Using specific terms simplifies calculations and enhances clarity, especially when dealing with processes involving varying amounts of the substance. This approach is particularly useful in engineering applications where the analysis is often performed on a per-unit-mass basis, allowing engineers to scale results up or down based on the mass of the working fluid.

The emphasis on specific terms in steam tables aligns with the standard practices in thermodynamics, where properties are often described per unit mass to facilitate the application of the first and second laws of thermodynamics across diverse systems.
