Kinetic Energy and Temp

JEE Main asked Kinetic Energy and Temp 11 times in 11 of the 108 shifts Lumi analysed, in 2020, 2021, 2022, 2023, 2024, 2025 and 2026. It belongs to Kinetic Theory of Gases, in Kinetic Theory (Physics). The longest wait between two years asking it was 1 year. In 2021, 2023 and 2024 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.
