Isobaric Process Analysis

JEE Main asked Isobaric Process Analysis 3 times in 3 of the 108 shifts Lumi analysed, in 2022, 2024 and 2025. It belongs to Thermodynamic Processes, in Thermodynamics (Physics). The longest wait between two years asking it was 2 years.

Questions on this idea a shift, by year

2017–2026. Asked in 2022, 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.

  • Match list on thermodynamic processes
  • Compare pressures from isobaric v-t graph
