Section 11 of 21

Thermodynamics

Properties, laws, cycles, mixtures, and the steam tables

What the section holds

The largest of the engineering science sections. Properties of single-component systems, PVT behaviour, the first law, basic cycles, psychrometrics, the second law, heats of reaction, vapor-liquid equilibrium, phase relations, chemical reaction equilibria, and refrigeration and HVAC cycles. The steam tables and the psychrometric and pressure-enthalpy charts are inside it.

Why it matters for your exam

Thermodynamics is examined on Chemical, Mechanical, Environmental and Other Disciplines specifications, and it is the section that grew in the most recent handbook revision. Its property tables are long, which is exactly why finding the right one fast matters.

How to navigate it

The section is mostly tables and charts after the first third. Learn where the steam tables begin and where the cycle diagrams sit relative to them, because scrolling through thirty pages of property data to find a chart is the classic thermodynamics time sink.

Page numbers here are read from handbook version 10.5 (seventh printing, April 2025), which runs to 502 pages. NCEES revises the handbook and page numbers move with it, which is why the drill asks which section a topic lives in rather than which page.
