Heat and Thermodynamics: SSC CGL Physics
Heat and Thermodynamics has six questions in the SSC CGL Tier I bank, two from each of the 2023, 2024 and 2025 shifts. They ask why steam burns worse, how a matka cools water, what a calorimeter is made of, and statements about the laws of heat. One page explains each with its reason.
The handout has every subtopic, worked example, formula and trap with answers shown. The formula sheet is the chapter’s formulas and traps alone, on one page.
