Verified manuals explicitly state which edition they match (e.g., "Compatible with the 8th Edition, 2014 reprint"). They include the problem number exactly as printed in your textbook.
Most free PDFs circulating on file-sharing sites (like Library Genesis or student Discord servers) are unverified. Here is the danger of using unverified solutions:

Before hunting for solutions, you must understand the book’s architecture. Most searches refer to the 7th Edition (McGraw-Hill, ISBN 0070170592), though the 8th edition exists.
The book is divided into five core parts: Verified manuals explicitly state which edition they match
A verified solution manual will cover odd-numbered problems (typically assigned to students) and, in the instructor’s edition, all problems—including the dreaded "challenge" problems at the end of Chapter 10 (Thermodynamic Relations).
Title: Heat and Thermodynamics
Authors: Mark W. Zemansky (deceased, original author) and Richard H. Dittman (revised 8th edition)
Edition: 8th Edition (most widely used; earlier editions: 1st–7th)
Publisher: McGraw-Hill
Typical course: Upper-level undergraduate thermodynamics in physics or engineering physics programs. A verified solution manual usually comes from: Before
The text is a classic, distinguished by:
Many professors place the official instructor’s solution manual on reserve in the physics library. You can photocopy the relevant chapters for your homework set.
