Adiabatic Process Analysis

JEE Main asked Adiabatic Process Analysis 16 times in 15 of the 108 shifts Lumi analysed, in 2020, 2021, 2022, 2023, 2024, 2025 and 2026. It belongs to Thermodynamic Processes, in Thermodynamics (Physics). The longest wait between two years asking it was 1 year. In 2021, 2022, 2023, 2024 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 2020, 2021, 2022, 2023, 2024, 2025 and 2026. Years differ in how many shifts Lumi analysed, so each year is scaled to one shift of 25 Physics questions.
