Cyclic Process Work

JEE Main asked Cyclic Process Work 7 times in 7 of the 108 shifts Lumi analysed, in 2021, 2023, 2024 and 2025. It belongs to Thermodynamic Processes, in Thermodynamics (Physics). The longest wait between two years asking it was 2 years. In 2021 and 2025 it came in more than one shift of the same year.

Questions on this idea a shift, by year

2017–2026. Asked in 2021, 2023, 2024 and 2025. Years differ in how many shifts Lumi analysed, so each year is scaled to one shift of 25 Physics questions.

How JEE Main framed it

Diagram based is the usual form. Skill tested: data or graph.

  • Net work in cyclic process on p-v diagram
  • Heat exchanged in multi-process gas cycle
